Multinucleon transfer reactions were employed in a series of experiments at Legnaro National Laboratories INFN and the Tandem Laboratory Horia Hulubei Institute Bucharest. The main aim was to investigate shape coexistence phenomenon even–even Sn isotopes, with mass \(A=112\)–118, through lifetime measurements excited \(0^+\) states. Recent Monte Carlo Shell Model (MCSM) calculations predict, fact, appearance well-separated secondary minima potential energy surfaces these corresponding...

Abstract Experimentally measured neutron activation cross sections are presented for the ( n , α ) and 2n reactions with detailed uncertainty propagation. The were at an incident energy of 14.92 ± 0.02 MeV, neutrons based on t d fusion reaction. reaction was used as a reference normalization flux. pre-calibrated lead-shielded HPGe detector to detect residues' γ -ray spectra. data from compared previously EXFOR database, theoretically calculated using TALYS EMPIRE codes, evaluated nuclear data.
Several experimental investigations have reported evidence of collective enhancement the nuclear level density and its fadeout. However, a suitable method is needed for determination factor as function excitation energy. In this study, neutron spectra were measured in coincidence with evaporated $\ensuremath{\alpha}$ particles produced reactions $^{11}\mathrm{B}+^{181}\mathrm{Ta},^{197}\mathrm{Au}$. The parameter has been extracted...
There have been great improvements in the predictions of nuclear masses, yet it is difficult to exactly reproduce measured mass. It has suggested that cause such discrepancies due negligence many-body effects available theoretical models. The errors prediction mass show residual correlations missing physics In present Letter we tried learn by using neural networks. We used a network architecture which adaptively learns linear and nonlinear between data different fidelity. finite range...

Abstract The pre-scission and post-scission neutron multiplicities are measured for the 18 O + 184 W reaction in excitation energy range of 67.23–76.37 MeV. Langevin dynamical calculations performed to infer dependence fission decay time compliance with multiplicities. Different models nuclear dissipation employed this purpose. Fission process is usually expected be faster at a higher beam energy. However, we found an enhancement average as incident increases. It happens because helps more...
