摘要:

本文报道了一种壳模型研究$2p1f$壳核中质子-中子配对的方法。通过在壳模型框架中工作,我们能够在不违反对称性的情况下评估核变形中质子-中子配对的各种模式的作用。给出了$^{44}$ Ti、$^{45}$ Ti、$^{46}$ Ti、$^{46}$ V和$^{48}$ Cr的结果,以评估质子-中子对相关性如何在不同情景下出现。我们还研究了如何存在一个单一的身体自旋轨道相互作用的影响的各种配对模式的贡献。

英文摘要:

A shell-model study of proton-neutron pairing in $2p1f$ shell nuclei using a parametrized hamiltonian that includes deformation and spin-orbit effects as well as isoscalar and isovector pairing is reported. By working in a shell-model framework we are able to assess the role of the various modes of proton-neutron pairing in the presence of nuclear deformation without violating symmetries. Results are presented for $^{44}$Ti, $^{45}$Ti, $^{46}$Ti, $^{46}$V and $^{48}$Cr to assess how proton-neutron pair correlations emerge under different scenarios. We also study how the presence of a one-body spin-obit interaction affects the contribution of the various pairing modes.
