Four-particle harmonic-oscillator transformation brackets : expression and fortran

Abstract

The wave function of a self-bound system in absence of external fields must be invariant in respect of spatial translations and antisymmetric respect of all permutations. Translational invariance of wave function means that it is dependent only on instrinsic degrees of freedom of the system. The traditional applications, such as the nuclear shell model, however, are based on a model Hamiltonian with individual one-particle variables. That wave functions are very attractive because they allow a simple procedure of antisymmetrization.[...]
