Author(s): J. B. Gupta and J. H. HamiltonThe recent data on $B(E2)$ values, deduced from the multi-Coulex excitation of the low spin states in the decay of $^{152}\mathrm{Sm}$, and other experimental findings in the last two decades are compared with the predictions from the microscopic dynamic pairing plus quadrupole model of Kumar and Ba...

Author(s): Swapan DasThe photonuclear reaction in the multi-GeV region occurs because of the electromagnetic and hadronic interactions. The latter originates due to the hadronic fluctuation, i.e., vector meson, of the photon. The total cross section of the reaction is shadowed because of the vector meson–nucleus (hadron...

Author(s): D. Cabrera, A. N. Hiller Blin, M. J. Vicente Vacas, and P. Fernández de CórdobaWe investigate the $ϕ$ meson nuclear transparency using some recent theoretical developments on the $ϕ$ in medium self-energy. The inclusion of direct resonant $ϕN$ scattering and the kaon decay mechanisms leads to a $ϕ$ width much larger than in most previous theoretical approaches. The model has b...

Author(s): K. Benrabia, D. E. Medjadi, M. Imadalou, and P.

Author(s): Neeraj Kumar, Shabnam Mohsina, Jhilam Sadhukhan, and Shashi VermaThe light-particle emission probability from an excited compound nucleus depends explicitly on the time-evolution of the system as the available internal excitation energy and, consequently, the particle decay widths depend on the instantaneous deformation of the nucleus. The Langevin dynamical mode...
