High speed store required:
5MK words
Number of bits in a word:
64
Number of lines in distributed program, including test data, etc:
279
Keywords:
Coulomb functions, Numerical integrations, General purpose.
Programming language used: Fortran
Computer:
DEC ALPHA 3000 .
Nature of physical problem:
Coulomb radial functions are required in problems involving interactions
between two charged particles. They depend on scaled variables: angular
momentum l; energy epsilon; radial co-ordinate r. Given either: a
Coulomb function and its derivative at one value of r and an accuracy
parameter, or an interval h = deltar, a function at two values of r
separated by h; the code calculates the function for a specified range
of r values [1].
Method of solution:
Numerov integrations.
Typical running time:
7.2s
Unusual features:
None
