✦ Synopsis

Titleof program: TAMOBR bracket, generalized harmonic oscillator bracket, harmonic oscillator Catalogue number: ABGR Nature of the physical problem Program obtainable from: CPC Program Library, Queen's The generalized harmonic oscillator brackets [11 form the University of Belfast, N. Ireland (see application form in this transformation matrix for the transition from the singleissue) particle coordinates to the cefitre of mass and relative coordinates in a two-particle harmonic oscillator basis. Unequal Computer: Installation: masses of particles are considered. IBM 370/135 Institute ofInformation, Theory and Automation, Prague Method of solution Recently published closed form for oscillator bracket [2j is EC 1040 Nuclear Research Institute, Kel used. Two subprograms are pitesented, one for the evaluation of a single bracket, the other for simultaneous calculation of a Operating system: OS/VS 1, OS/ES set of brackets with fixed angular momenta. Programming language used: FORTRAN IV Restrictions of the complexity of the problem Restrictions are given by the size of the core storage assigned High speed storage required: 16 896 words to dimensioned quantities. The present version allows the computation ofoscillator brackets with max(l, L, l~, '2) = 13 Number of bits in a word: 32 and max(n + N, n 1 + n2) =32. Overlay structure: none Typical running time Roughly 100 brackets per second on the IBM 370/135 corn-No. of magnetic tapesrequired: none puter Other peripherals used: card reader and line printer Unusualfeatures of the program Double precision REAL*8 arithmetic is used on computers Number of cards in combined program and test deck: 609 with 32 bit words.
