mod_regsol Module

Calculates the regular solution of the schroedinger equation or ! in semi relativistic approximation for a spherically averaged potential and given en !ergy. To archieve greater presion the leading power $r^s$ (in schro !edinger case s = l, in case of sra $s = \sqrt{ (l^2+l-1) - \frac{4z^2}{c^2} } )$ !is analytically separated from the wavefunction. The t-matrix has to be determined at the mt radius in case of a ! mt calculation or at the ws radius in case of a ws calculation. Therefore the !logarithmic derivative is calculated at that point (=ircut(ipan) )
