摘要/Abstract

摘要： 介绍一个新的IBM-2程序。它以F旋对称的U(5)极限的波函数做为基,并将Hamiltonian写成F旋张量的形式。除了通常的显含质子中子指标的Hamitonian的输入外,还有F旋张量的形式输入。并且能够计算B(E2)和B(M1)。

关键词: 核结构, F-旋, 质子中子相互作用玻色子模型

Abstract: A computer package for the neutron-proton interacting boson model is presented.It used the F-spin symmetric U(5) limit wavefunction as its basis states.Hamiltonian and other operators are written in terms of F-spin tensorial form.In the input,in addition to the hamiltonian forms in terms of neutron and proton bosons indices,F-spin tensorial formalism is also provided.B(M1) and B(E2) can also be calculated in the package.

Key words: nuclear structure, F-spin formalism, neutron-proton interacting boson model
