摘要
介绍一个新的IBM2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)。
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.
