LABORATORI NAZIONALI DI LEGNARO
Investigation of dynamical effects in heavy-ion induced fusion reactions is an area of intense research. Much progress has been made in this field both on the theoretical and experimental front. In some of the recent experimental studies, it is observed that the light particles spectra from the compound nucleus populated through asymmetric systems could be explained by standard statistical model calculations, whereas the spectra from the symmetric systems could not be explained by these calculations. These studies indicated the presence of dynamical effects in fusion leading to non-fusion of higher values of angular momentum and a delay in the fusion process. This delay or fusion hindrance results in the pre-equilibrium emission of light particles. But most of the existing measurements are inclusive and conclusions are made using one observable only. We have performed the exclusive light particle evaporation spectra measurements and have used more sensitive probes like fusion cross-sections and spin distribution measurements for investigating the dynamics of heavy-ion induced fusion reactions. I will be discussing about the light particle evaporation spectra and fusion cross-section measurements in the present seminar.
