The four-particle harmonic-oscillator brackets: Compact expressions and updated Fortran program. (English) Zbl 1262.81263

Summary: We present a new version of the four-particle harmonic-oscillator transformation brackets (4HOB) calculation program, where marginal cases of mass-ratio parameters \(d=0\), \(d\to \infty\) and \(d_1=0\), which cannot be calculated with previous version, are presented. The simplified 4HOB calculation formulas for these cases are given.
