Nature of problem:
The oscillator brackets are used in various aspects of nuclear structure and reaction calculations. Our program calculates these very rapidly.

Solution method:
The method is to use a closed form for an oscillator bracket as given by Baranger and Davies, and then to calculate simultaneously a large number of brackets that have different sets of principal quantum numbers for a given set of angular-momentum quantum numbers.

Restrictions:
Restrictions come about only through the size of the core storage assigned by the DIMENSION statements. The storage presently assigned will meet the needs of most present day nuclear physics calculations.

Running time:
The running time of the program ranges roughly from 600 to 1000 brackets per second of CP time on the CDC 6600 computer at the computer center of the University of Texas.
