Neutrons tunneling to the classically forbidden (CF) region in the neutron-rich nucleus are investigated in the Skyrme Hartree-Fock (HF) and Hartree-Fock-Bogoliubov (HFB) models. The definition of the CF region is examined in the HF model by using different single-particle potentials for the bound states. In the HFB model, the weakly bound and continuum states could also contribute to the neutrons in the CF region due to the pairing correlation. Their asymptotic wave functions are carefully calculated by the Green’s function method.

富中子核68Ca经典禁区中子研究 国家留学基金委资助(201906255002)

在 Skyrme Hartree-Fock (HF) 和 Hartree-Fock-Bogoliubov (HFB) 模型中研究了隧道到富中子核中经典禁止 (CF) 区域的中子。CF 区域的定义在 HF 模型中通过对束缚态使用不同的单粒子势来检查。在 HFB 模型中，由于配对相关性，弱束缚态和连续态也可能对 CF 区域中的中子有贡献。它们的渐近波函数是通过格林函数方法仔细计算的。
