用Skyrme-Hartree-Fock-Bogoliubov理论实现奇偶质量交错

Odd-even mass staggering with Skyrme-Hartree-Fock-Bogoliubov theory

W. J. Chen, C. A. Bertulani, F. R. Xu, Y. N. Zhang

摘要:

本文利用Skyrme-Hartree-Fock-Bogoliubov理论,采用等势接触对相互作用和等矢接触对相互作用,研究了核的奇偶质量交错。通过再现经验的奇偶质量差的Sn同位素链,配对相互作用的强度被确定。通过调整得到的最佳强度比通过重现$^{120}$ Sn的实验中子对能隙得到的最佳强度更能描述奇偶质量差。

英文摘要:

We have studied odd-even nuclear mass staggering with the Skyrme-Hartree-Fock-Bogoliubov theory by employing isoscalar and isovector contact pairing interactions. By reproducing the empirical odd-even mass differences of the Sn isotopic chain, the strengths of pairing interactions are determined. The optimal strengths adjusted in this work can give better description of odd-even mass differences than that fitted by reproducing the experimental neutron pairing gap of $^{120}$Sn.
