Nature of problem:
The program calculates total, single and double differential cross sections for the single ionization of hydrogen-like atoms/molecules and helium-like atoms by light-or-heavy-ion impact, where the projectile ions are assumed to be structureless.
The program allows the user to calculate cross sections using the CDW or CDWW-EIS  approximations within the wave treatment. The cross sections are evaluated using the QUADPACK subroutines QAGE, QK15 and QK61 .
Times vary according to input data. The average time taken to evaluate the double differential cross section for eight points of energy is 23 seconds, while using only one processor takes approximately 65 seconds.
