A. S. Umar, V. E. Oberacker

摘要:

我们利用最近引入的密度约束含时Hartree-Fock方法研究了$^{64}$ Ni+ $^{132}$ Sn体系的熔合反应.在这种形式主义的融合壁垒直接从TDHF动力学。此外,我们纳入变形(扁)$^{64}$ Ni核由于动态库仑激发的入口通道对齐。我们讨论了粒子转移和其他动力学效应对熔合截面的影响。计算的截面与数据和其他计算结果非常吻合。

英文摘要:

We study fusion reactions of the $^{64}$Ni+$^{132}$Sn system using the recently introduced density constrained time-dependent Hartree-Fock formalism. In this formalism the fusion barriers are directly obtained from TDHF dynamics. In addition, we incorporate the entrance channel alignment of the deformed (oblate) $^{64}$Ni nucleus due to dynamical Coulomb excitation. We discuss the influence of particle transfer and other dynamical effects on the fusion cross sections. Calculated cross sections are in very good agreement with data and other calculations.
