Operating system: NOS/BE 1.3.
RAM: 40K words
Word size: 60
Peripherals: disc.
Keywords: Nuclear physics, Integrals over angles, Partial-wave expansion, Word addressable files, Cluster model.
Classification: 17.21.

Nature of problem:
Matrix elements of operators between Slater determinants of two-cluster structures must be expanded into partial waves for the purpose of angular momentum projection. The expansion coefficients contain integrals over the spherical angles theta and psi.

Solution method:
All integrals needed (see program PRO2C) are calculated using analytical formulae and stored in a file with the CDC Word Addressable organization. This file is used by the program PRO2C.

Restrictions:
No restrictions of physical nature.

Unusual features:
A disk file with CDC Word Addressable organization is used (with the Record Manager routines).

Running time:
1.1 s for the test run.
