[en] The production and use of energetic radioactive beams is a rapidly developing field in nuclear physics. Pioneering experiments are taking place, dedicated facilities are being commissioned and new facilities are planned. The aim of the Euroschool on Exotic Beams is to introduce PhD students and young post-doctoral researchers to this field and also present recent experimental and theoretical advances. Each school consists of a number of lecture courses given by specialists in the field, starting from a basic level but also including more advanced seminars. This document gathers only the slides of 5 presentations: 1) Ground-state properties from laser spectroscopy and radioactive ion beam facilities and their experimental techniques, 2) Progress in fission, 3) Nuclear shapes, 4) Nuclear data for Astrophysics and 5) Nuclear Astrophysics - experimental aspects

[en] The light Krypton isotopes were studied in a series of Coulomb excitation experiments using radioactive beams at GANIL. The static quadrupole moments found in these experiments give firm experimental evidence for the shape coexistence scenario that is based on theoretical calculations and on the systematics of low-lying excited 0⁺ states.

[en] The yrast states were observed up through both the first and second band crossings in both ¹¹²Ru and ¹¹⁶Pd using the ²³⁸U(α, f) fusion-fission reaction. The rotational alignment of the g_9/2 proton-pair is responsible for the second band crossing. This assignment is based on the amount of angular momentum gained in the alignment and a similar crossing frequency is observed for the rotational band based on the h_11/2 neutron orbital in both ¹¹¹Ru and ¹¹⁷Pd. The closeness of the crossing frequency between the first and second band crossings, which happens unexpectedly within a rotational frequency span of ∼50 keV, most likely is caused by a transition of a triaxial shape from prolate to oblate in neutron rich Ru and Pd nuclei

[en] The compound nucleus ¹⁶⁸Hf was populated in three fusion-evaporation reactions with different beam-target mass asymmetries: ⁵⁰Ti+¹¹⁸Sn, ⁶⁴Ni+¹⁰⁴Ru and ⁷⁴Ge+⁹⁴Zr. Due to the large negative Q values of these reactions the compound nucleus is formed at low excitation energy. At three or four excitation energies for each reaction γ-ray spectra of the evaporation residues ¹⁶⁶Hf to ¹⁶³Hf, corresponding to the 2n to 5n exit channels, respectively, were recorded with the Ge detectors of the 8π-spectrometer array. The γ-ray multiplicity and total energy were measured using the inner ball of BGO detectors. This data was used to determine the maximum angular momentum transferred to each evaporation channel, the γ-ray decay entry region and the relative cross sections. No differences are observed between the three reactions. This is explained by the very similar dependence of the excitation energy on the angular momentum of the compound nucleus. The relative cross sections for the 2n and 3n channels are observed to be significantly larger than predicted by statistical model calculations

[en] The purpose of this Rapid Communication is to show that recent data on the ground-state band and excited states based on the 0₂⁺ level in ¹⁵⁰Nd and ¹⁵²Sm, especially the measured B(E2) values, can be well described by including a ΔK=0 coupling between rotational bands. This is contrary to recent statements in the literature. The experimental data are compared with models that have supported the widely differing interpretations of these transitional nuclei. These interpretations include describing excited states as rotational excitations of single-phonon states, the multiphonon 'phase coexistence' picture, and the X(5) critical-point description

[en] In a mixture of three Yb nuclei, we find the rotational damping widths vary from 180 keV at 1.1 MeV γ-ray energy to 290 keV at 1.5 MeV, and the average compound damping widths (or spreading widths) vary from 40 keV at 1.1 MeV γ-ray energy to 60 keV at 1.3 MeV. The simulations also suggest extensive motional narrowing
