摘要:

本文用三体Faddeev方法研究了一般中子-中子-核系统的Efimov激发态的行为,其中中子-核是束缚的,中子-中子是非束缚的,考虑了零程和有限程两体相互作用.对于有限范围的相互作用,我们考虑了一项可分离的山口势。主要目的是研究范围修正的缩放方法,重点是在异国情调的碳晕核$^{20}C$。

英文摘要:

The behaviour of an Efimov excited state is studied within a three-body Faddeev formalism for a general neutron-neutron-core system, where neutron-core is bound and neutron-neutron is unbound, by considering zero-ranged as well as finite-ranged two-body interactions. For the finite-ranged interactions we have considered a one-term separable Yamaguchi potential. The main objective is to study range corrections in a scaling approach, with focus in the exotic carbon halo nucleus $^{20}C$.
