Calculation of five-particle harmonic-oscillator transformation brackets

Abstract

In this work we present a FORTRAN code for the calculation of the matrix of the orbital fractional parentage coefficients for five particles (5HOB) in a translationally invariant basis. Our code calculates the 5HOB eigenvector matrix M and the diagonal eigenvalue matrix F . The full 5HOB matrix is obtained from these matrices. Program summary. Program title: 5hob_serial.

Nature of problem: Calculation of five-particle harmonic-oscillator transformation brackets matrix. Solution method: The method is based on compact expressions of the five-particle harmonics oscillator brackets (5HOB), presented in [1]. Additional comments including restrictions and unusual features: For theoretical issues of revision see section ‘Theoretical aspects’ and for more detailed information see [1].
