“…Many experimental studies have been performed to understand the mechanisms at play in the quasi-fission process since its discovery [11][12][13][14][15][16][17][18][19]. Various theoretical models [20][21][22] have also been developed to help in the interpretation of these experimental data.…”

“…havior may be due to the fact that Zr isotopes (Z = 40) in the mass range 100 − 112 are strongly bound with a large prolate deformation around β 2 = 0.42 [48][49][50]. Due to shell effects, these configurations may be energetically favorable during the QF dynamics [16,17,19]. A similar effect is observed in TDHF calculations of collisions with the tip of 238 U which favors the formation of fragments in the vicinity of the doubly magic 208 Pb nucleus [39].…”

“…Due to the low intensity of radioactive beams and low neutron fluxes in existing nuclear reactors the second and third methods seem to be unrealizable. On the contrary, the low-energy multi-nucleon transfer reactions, as well as the quasi-fission processes [4] (which are similar) are quite practical. These processes are less studied as compared with well studied few nucleon transfer reactions (see for example review paper [5]).…”

Abstract. The present limits of the upper part of the nuclear map are very close to stability while the unexplored area of heavy neutron-rich nuclides along the neutron closed shell N = 126 below 208 Pb is extremely important for nuclear astrophysics investigations and, in particular, for the understanding of the r-process of astrophysical nucleosynthesis. This area of the nuclear map can be reached neither in fusion-fission reactions nor in fragmentation processes widely used nowadays for the production of exotic nuclei. A new way was recently proposed for the production of these nuclei via low-energy multi-nucleon transfer reactions. The estimated yields of neutron-rich nuclei are found to be significantly high in such reactions and several tens of new nuclides can be produced, for example, in the near-barrier collision of 136 Xe with 208 Pb. A new setup is proposed to produce and study heavy neutron-rich nuclei located along the neutron closed shell N=126.

“…Two kinds of shell-effects on the di-nuclear system have been observed. The first one is due to shell closures in the entrance channel [28], the second one, as studied here in the case of fusion fission, is due to shell-effects in final fragments [29][30][31]. It is known that with the increase in excitation energy, nuclear shell effect decreases.…”

Abstract. Using the major accelerator facilities available in India, detailed experimental studies have been made to understand the mechanism of quasi-fission and role of nuclear shell effect in heavy nuclei. Fission fragment mass distribution has been used as the probe to explore the role of entrance channel effects on fusion-fission and quasifission dynamics. Fission fragment mass distribution has also been demonstrated to be useful to identify the phenomenon of 'washing out' of nuclear shell effect with excitation energy.
