Production of the exotic neutron-deficient isotopes near N, Z = 50 in multinucleon transfer reactions

Abstract

The multinucleon transfer reaction in the collisions of ${}^{40}$Ca+${}^{124}$Sn at $E_{\text{c.m.}}=128.5$ MeV is investigated by using the improved quantum molecular dynamics model. The measured angular distributions and isotopic distributions of the products are reproduced reasonably well by the calculations. The multinucleon transfer reactions of ${}^{40}$Ca+${}^{112}$Sn, ${}^{58}$Ni+${}^{112}$Sn, ${}^{106}$Cd+${}^{112}$Sn, and ${}^{48}$Ca+${}^{112}$Sn are also studied. It shows that the combinations of neutron-deficient projectile and target are advantageous to produce the exotic neutron-deficient nuclei near $N,Z$ = 50. The charged particles emission plays an important role at small impact parameters in the deexcitation processes of the system. The production cross sections of the exotic neutron-deficient nuclei in multinucleon transfer reactions are much larger than those measured in the fragmentation and fusion-evaporation reactions. Several new neutron-deficient nuclei can be produced in ${}^{106}$Cd+${}^{112}$Sn reaction. The corresponding production cross sections for the new neutron-deficient nuclei, ${}^{101,102}$Sb, ${}^{103}$Te, and ${}^{106,107}$I, are 2.0 nb, 4.1 nb, 6.5 nb, 0.4 $\mu$b and 1.0 $\mu$b, respectively.
