Manuscript Title: Calculations of generalized harmonic oscillator brackets. | ||

Authors: J. Dobes | ||

Program title: TAMOBR | ||

Catalogue identifier: ABGR_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 16(1979)373 | ||

Programming language: Fortran. | ||

Computer: IBM 370/135. | ||

Operating system: OS/VS1, OS/ES. | ||

RAM: 17K words | ||

Word size: 32 | ||

Keywords: Nuclear physics, Reaction, Two-body operator Matrix elements, Talmi-moshinsky bracket, Harmonic generalized Oscillator bracket, Harmonic oscillator. | ||

Classification: 17.17. | ||

Nature of problem:The generalized harmonic oscillator brackets form the transformation matrix for the transition from the single-particle coordinates to the centre of mass and relative coordinates in a two-particle harmonic oscillator basis. Unequal masses of particles are considered. | ||

Solution method:Recently published closed form for oscillator bracket is used. Two subprograms are presented, one for evaluation of a single bracket, the other for simultaneous calculation of a set of brackets with fixed angular momenta. | ||

Restrictions:Restrictions are given by the size of the core storage assigned to dimensioned quantities. The present version allows the computation of oscillator brackets with max(l,L,l1,l2) = 13 and max(n+N,n1+n2) = 32. | ||

Unusual features:Double precision REAL*8 arithmetic is used on computers with 32 bit words. | ||

Running time:Roughly 100 brackets per second on the IBM 370/135 computer. |
