Possibilities for synthesis of new neutron deficient isotopes of superheavy nuclei

• In order to search the optimal projectile-target combination to produce new neutron deficient isotopes of superheavy nuclei (SHN), the dependence of the evaporation residue cross section (ERCS) to synthesize SHN on the mass asymmetry and the isospin of colliding nuclei are analysed within the dinuclear system (DNS) concept. Predicted ERCSs for the production of new neutron deficient isotopes of SHN were found to be quite large with 36S projectile, and it is found that the production cross sections of SHN decrease slowly with the charged numbers of compound nuclei due to the increases in survival probability which $W_{{\rm sur}}$ are not canceled by the decreasing $P_{{\rm CN}}$.

Abstract: In order to search the optimal projectile-target combination to produce new neutron deficient isotopes of superheavy nuclei (SHN), the dependence of the evaporation residue cross section (ERCS) to synthesize SHN on the mass asymmetry and the isospin of colliding nuclei are analysed within the dinuclear system (DNS) concept. Predicted ERCSs for the production of new neutron deficient isotopes of SHN were found to be quite large with 36S projectile, and it is found that the production cross sections of SHN decrease slowly with the charged numbers of compound nuclei due to the increases in survival probability which $W_{{\rm sur}}$ are not canceled by the decreasing $P_{{\rm CN}}$.
