摘要：
The dinuclear system approach, coupled with the statistical decay model GEMINI++, was used to investigate multinucleon transfer reactions. Experimental production cross-sections in the reaction( 129)Xe+Cm-248 were reproduced to assess the reliability of these theoretical models. The production of neutron-deficient transcalifornium nuclei with Z=99-106 was examined in multinucleon transfer reactions, including Xe-124 + Cm-248, Xe-124 +Cf-249, and Xe-129+ Cf-249. Both the driving potential and the neutron-to-proton equilibration ratio were found to dominate the nucleon transfer process. The reaction Xe-124 +Cf- 249 is proposed as a promising projectile-target combination for producing neutron-deficient isotopes with Z=99-106, with the optimal incident energy identified as E-c. m.=533.64 MeV. Production cross-sections of 25 unknown neutron-deficient trancalifornium isotopes with cross-sections greater than 1 pb were predicted.
