Nature of physical problem:
Calculation of exact matrix elements between hydrogenic states perturbed
by linearly or circularly polarized laser light. The different
functions which are called by the main code, fnodipol, allows the
evaluation of the radial hydrogen wavefunction and its derivative,
spherical harmonics, the integral of a product of three spherical
harmonics, 3-j symbols and Clebsch-Gordan coefficients.
Method of solution
Rectangular integration based on numerical evaluation of the radial
wavefunctions and plane wave expansion of the light field.
Restrictions on the complexity of the program
Only quantum numbers up to n=30 has been tested on our installation.
More careful evaluation of hydrogenic states is needed at even higher n
(and low l) quantum numbers.
Typical running time
From seconds to minutes depending on the number of mesh-points.
