单$l-$壳层模型中的中子-质子配对关联

Neutron-proton pairing correlations in a single $l-$shell model

A. Márquez Romero, J. Dobaczewski, A. Pastore

摘要:

采用Hartree-Fock-Bogoliubov形式,在粒子-空穴和粒子-空穴通道中考虑中子-质子混合,重新讨论了长期存在的中子-质子配对关联问题.我们比较数值计算中进行这种方法与精确的配对模型的基础上的$SO(8)$代数。在我们的计算中,中子-质子混合是通过在同位旋空间中使用等排列技术进行旋转来计算的。

英文摘要:

The long standing problem of neutron-proton pairing correlations is revisited by employing the Hartree-Fock-Bogoliubov formalism with neutron-proton mixing in both the particle-hole and particle-hole channels. We compare numerical calculations performed within this method with an exact pairing model based on the $SO(8)$ algebra. The neutron-proton mixing is included in our calculations by performing rotations in the isospin space using the isocranking technique.
