标题： Jost function based on the Hartree-Fock-Bogoliubov formalism

摘要： 我们基于哈特里-福克-博戈柳博夫（HFB）理论提出Jost函数形式，该理论已被用于表示核超流性的本质。基于HFB的Jost函数可以给出考虑配对效应的核子弹性散射针对开放壳核的S矩阵的解析表示。通过采用Woods-Saxon势，我们在费米能级的两种情况下，展示了随着配对强度变化的S矩阵极点及其轨迹的数值结果。还分析了每种情况下中子弹性散射的总截面，并确认在截面中可以看到由配对效应引起的某些阶梯形状或尖锐共振。 显示英文摘要

摘要： We formulate the Jost function formalism based on the Hartree-Fock-Bogoliubov (HFB) theory which has been used to represent the nature of the superfluidity of nucleus. The Jost function based on the HFB can give the analytic representation of the S-matrix for the nucleon elastic scattering targeting on the open-shell nucleus taking into account the pairing effect. By adopting the Woods-Saxon potential, we show the numerical results of S-matrix poles and their trajectories with varying the pairing strength in two cases of Fermi energies. The total cross sections in each cases for neutron elastic scattering are also analyzed, and we confirmed some staggering shapes or sharp resonances originated from the effect of pairing can be seen in the cross section.
