AbstractAbstract
[en] A 4π light charged particle spectrometer, named 8πLP, is in operation at the Laboratori Nazionali di Legnaro, Italy, for the study of the reaction mechanisms produced in low energy heavy ion reactions. Besides the about 300 telescopes to detect light charged particles, the spectrometer is also equipped with an annular PPAC system to detect evaporation residues and a two-arm Time-of-Flight spectrometer to detect fission fragments. The spectrometer has been used in several studies on fission dynamics using as a probe light charged particles in the fission and evaporation residues channels. This presentation will propose a journey within the open questions about the fission dynamics and will review the main results concerning nuclear dissipation and the fission time scale obtained from several of these studies. In particular the advantages of using systems of intermediate fissility will be discussed

AbstractAbstract
[en] A report indicates that the effect of transfer breakup is significant compared to direct breakup. As 7Li has larger breakup threshold compared to 6Li, it is interesting to see the origin of α particle from breakup/transfer and their contribution towards the breakup cross-sections. The present work describes an experiment, measuring the α-particle (inclusive/exclusive) yield from 7Li+208Pb reaction

AbstractAbstract
[en] The differential cross-section for different channels for "7Li+"2"0"8Pb reaction at 33 MeV have been presented. The inclusive α is larger than the exclusive α (α from other channels in coincidence) and also the contribution of α + α are more significant than α+t channels. Which conclude that other reaction mechanisms that provides significant amount of α to the inclusive cross section need further study

AbstractAbstract
[en] In the present work we have investigated the elastic scattering of the system 7Li + 208Pb at lab energies ranging from below to above the Coulomb barrier. 7Li is a weakly bound nucleus having breakup threshold in (α+t) of 2.47 MeV, just 1 MeV above the breakup threshold of 6Li (α+d). So it would be interesting to see how the BU of 7Li will affect the elastic scattering compared to 6Li case which has a larger breakup probability

AbstractAbstract
[en] Reaction mechanism involving weakly bound nuclei is of continue interest due to its wide range of anomalous behavior in experimental observables, an effect due to low breakup threshold. Over the last decade, with the availability of secondary radioactive ion beams, understanding the role of breakup has become a major research focus. Projectile dissociation in the field of target nucleus is a topic of continued interest because of its application to the determination of radiative capture cross section of astrophysical interest. Projectile breakup modifies the accepted picture for two body fusion of strongly bound nuclei. In this report we presented a completely different and simple approach to understand the breakup mechanism using loosely bound nuclei. A 3 body decay mechanism has been simulated using Monte Carlo technique to understand the breakup phenomena. This is a continuation of our previous investigation

AbstractAbstract
[en] A 4π-spectrometer of light charged particles, named 8πLP, is in operation at the Legnaro National Laboratory (Italy) for studying mechanisms of heavy ions production during low-energy reactions. The spectrometer has been used recently for analysis of fission dynamics, which involved transfer of light charged particles to fission and to the channel of residue evaporation in the system of intermediate fissionability and study of multinucleon transfer to heavy target. Data on the system 240 MeV 32S + 100Mo are provided. Dynamic effects stemming from comparison of the data with statistical model of calculations are discussed

AbstractAbstract
[en] In this report we present the different outgoing channel leading to break-up of the projectile in coincidence condition at the beam energy of 35 MeV for the "7Li+"2"0"8 Pb system. An interpretation of α spectra from projectile break-up will be discussed. It will shed light on the implications of the higher binding energy of "7Li on the exclusive break-up. This is a continuation of our previous investigation

AbstractAbstract
[en] Transmission coefficients calculated by optical model (OM) and ingoing-wave boundary-condition model (IWBCM) are discussed from the theoretical point of view an then compared with experimental findings. IWBCM appears to be more appropriate in describing particle evaporation as OM includes confusion processes in the inverse reaction, mainly for deuterons and tritons. This conclusion is supported by the comparison with 1,2,3H, 4He yields and energy spectra in the reaction 180-MeV 32S + 64Ni. In particular, IWBCM transmission coefficients provide, as expected, a better overall agreement with the data, with respect to the optical model ones, as these latter systematically over-predict 2,3H yields. Preliminary results of a similar analysis on other systems are also reported. (authors)
