Abstract

The partial wave expansion of the Coulomb-distorted plane wave is determined by the help of the complex generalized hypergeometric function 2F2(a,a;a+l+1,a-l;z). An algorithm for the calculation of 2F2(a,a;a+l+1,a-l;z) is created and it is implemented as a FORTRAN-90 code. The code is fast and its accuracy is 14 significant decimal digits.
