摘      要：In this article,a comprehensive study of the fission process of Th,U,Pu,and Cm isotopes using a Yukawa-folded meanfield plus standard pairing model is *** study focused on analyzing the effects of the pairing interaction on the fragment mass distribution and its dependence on nuclear *** significant role of pairing interactions in the fragment mass distributions of^(230)Th,^(234)U,^(240)Pu,and^(246)Cm was *** analysis revealed that increasing the pairing interaction strength decreased the asymmetric fragment mass distribution and increased the symmetric ***,the odd-even mass differences at symmetric and asymmetric fission points were examined,highlighting their sensitivity to changes in the pairing interaction *** analysis of the Th,U,Pu,and Cm isotope fragment mass distributions demonstrated the effectiveness of the model in reproducing the experimental *** addition,the effects of the zero-point energy and half-width parameter on the fragment mass distribution for^(240)Pu were ***,this study provides valuable insights into the fission process by emphasizing the importance of pairing interactions and their relationship with nuclear elongation.
