[en] The International Nuclear Physics Conference (INPC) is the main conference in the field of nuclear physics, endorsed and supported by IUPAP (International Union of Pure and Applied Physics). It is held every 3 years and the present edition INPC 2013 was the 25. of the series. INPC-2013 addressed the most compelling questions of modern nuclear physics, including nuclear structure and reactions, hot and dense nuclear matter, astrophysics, hadron structure and hadrons in nuclei, fundamental symmetries and interactions, neutrinos and nuclei, nuclear physics based applications as well as new facilities and instrumentation. The Conference was attended by more than 700 participants from 43 countries. This issue of EPJ Web of Conferences contains most part of the plenary, invited, oral and poster contributions given at INPC-2013

[en] Parton distribution functions, describing longitudinal momentum, helicity and transversity distributions of quarks and gluons, have been recently generalized to account also for transverse degrees of freedom. Two new sets of more general distributions, Transverse Momentum Distributions (TDM) and Generalized Parton Distributions (GPD), were introduced to describe transverse momentum and space distributions of partons. Great progress has been made since then in measurements of different Single Spin Asymmetries (SSAs) in semi-inclusive and hard exclusive processes providing access to TMDs and GPDs, respectively. Facilities world-wide involved in studies of the 3D structure of nucleon include HERMES, COMPASS, BELLE, BaBar, Halls A, B, and C at JLab, and PHENIX and STAR at RHIC (BNL). TMD studies in the Drell-Yan process are also becoming an important part of the program of hadron scattering experiments. Studies of TMDs are also among the main driving forces of the JLab 12-GeV upgrade project, several of the forward upgrade proposals of STAR and PHENIX at RHIC, and future facilities, such as the Electron Ion Collider (EIC), FAIR in Germany, and NICA in Russia. In this contribution we present an overview of the latest developments in studies of parton distributions and discuss newly released results, ongoing activities, as well as some future measurements.

[en] To study the β-decay properties of some well known delayed neutron emitters an experiment was performed in 2009 at the IGISOL facility (University of Jyvaeskylae in Finland) using Total Absorption γ-ray Spectroscopy (TAGS) technique. The aim of these measurements is to obtain the full β-strength distribution below the neutron separation energy (S_n) and above the γ/neutron competition. This piece of information is a key parameter in nuclear technology applications as well as in nuclear astrophysics and nuclear structure. Preliminary results of the analysis show a significant γ-branching ratio above S_n and this surprising result is in contradiction with the general assumption of neutron emission domination above S_n

[en] Nuclei like "3"4","3"5Al are lying at the boundary of the 'Island of Inversion' and little experimental information about their ground state configurations is available in literature. Neutron-rich "3"4","3"5Al isotopes have been studied through Coulomb excitation using LAND-FRS setup at GSI, Darmstadt. The method of invariant mass analysis has been used to reconstruct the excitation energy of the nucleus prior to decay. Comparison of experimental Coulomb dissociation cross-section with direct breakup model calculation with neutron in p3/2 orbital favours "3"4Al(g.s)*p3/2 where * means convolution product, as ground state configuration of "3"5Al. But the ground state configuration of "3"4Al (N=21) is more complicated as it appears from observed γ-ray spectra of "3"3Al obtained after Coulomb breakup of "3"4Al

[en] A rapid onset of quadrupole deformation is known to occur around the neutron number 60 in the neutron-rich Zr and Sr isotopes. This shape change has made the neutron-rich A = 100 region an active area of experimental and theoretical studies for many decades now. We report in this contribution new experimental results in the neutron rich "9"6","9"8Sr investigated by safe Coulomb excitation of radioactive beams at the REX-ISOLDE facility, CERN. Reduced transition probabilities and spectroscopic quadrupole moments have been extracted from the differential Coulomb excitation cross section supporting the scenario of shape coexistence/change at N=60. Future perspectives are presented including the recent experimental campaign performed at ILL-Grenoble. (authors)

[en] In this work, electron-capture rates on nuclei for stellar conditions are calculated for Ni isotopes, using a self-consistent microscopic model based on the finite-temperature Skyrme Hartree-Fock plus finite-temperature charge-exchange random-phase approximation approach. The results of the calculations show that electron-capture rates obtained either with different Skyrme sets or with different available models can differ by up to a few orders of magnitude.

[en] The even-even Cd isotopes have long been cited as one of the prime examples of vibrational behaviour, identified soon after the Bohr model was developed in the early fifties. By the late 1970's, the presence of intruder states and shape coexistence were identified, but the underlying vibrational nature remained intact. More recently, the robustness of the multiphonon states was questioned, prompting detailed spectroscopic investigations at a number of facilities, including the use of the (n, n' γ) reaction and β- decay studies with modern γ-ray spectrometers. Combining results from these studies, a re-examination of the structure of the mid-shell Cd isotopes suggests that they may represent deformed γ-soft rotors rather than spherical vibrators.

[en] The nuclear symmetry energy is a basic ingredient of the nuclear equation of state: it accounts for the energy cost per nucleon to convert all protons into neutrons in symmetric nuclear matter. Experimental and theoretical efforts are being devoted to the study of observables that can shed light on the properties of the nuclear symmetry energy. We present our new results on the excitation energy and polarizability of the Isovector Giant Quadrupole Resonance (IVGQR), which has been the object of new experimental investigation. We also present our theoretical analysis on the parity violating asymmetry at the kinematics of the Lead Radius Experiment (PREx) and highlight its relation with the density dependence of the symmetry energy. Most results deal with "2"0"8Pb nucleus

[en] We have carried out a new experiment with "1"2Be secondary beam at 29 MeV/u. The molecular resonant states were reconstructed from "4He-"8He and "6He-"6He decaying channels. These states agree well with previously reported results by Freer et al., and therefore support the highly disputed clustering structure of "1"2Be. Cross sections for these two breakup channels were also deduced to be (0.14 ± 0.03) mb and (0.65 ± 0.10) mb for the "6He + "6He and "4He + "8He decaying channels, respectively, which are reasonably consistent with previous results with a similar detector system

[en] We employ a transport model based on the Landau-Vlasov equation to explore the dipolar response of neutron-rich systems and its dependence on the symmetry energy. We present evidences for collective features of the Pygmy Dipole Resonance (PDR) and study its dependence with the mass number. We extract a parametrization for the energy centroid position, 41*A"-"1"/"3, which agrees quite well with the data for Ni, Zr, Sn and Pb. A linear correlation between the Energy Weighted Sum Rule (EWSR) associated to PDR and the neutron skin thickness is evidenced. An increase of 15 MeV fm"2 of EWSR to a change of 0.1 fm of neutron skin size is obtained. We conclude that different nuclei having close neutron skin size will exhaust the same EWSR in the pygmy region. Consequently a precise experimental estimate of total EWSR exhausted by PDR allows the determination of the neutron skin size and the constrain of the slope parameter of the symmetry energy. (authors)
