Description

Title of program: CONTRACTION-BASIC-DIAGRAM Catalogue Id: ACZI_v1_0 Nature of problem Operators, referred to here as basic operators, such as Hamiltonian, electromagnetic transition and nucleon transfer, are defined in terms of products of single particle creation and annihilation operators (and their matrix elements). In many physical problems, it is necessary to evaluate the scalar and configuration traces of a product of basic operators. The easiest way to achieve this is to find all the diagrams, i.e., complete contractions among the single particle operators. Because of symm ...
