Program xsec

This program computes T matirces which are combinations of K matrix elements obtained using the exact exchange potential for low l partial waves and matrix elements with high values of l computed using a purely local potential approximation. The program can read a combination of T and K matrix elements and correctly handle them. After the program has combined the matrices in the T matirx form, the matrices are transformmed back into the K matirx form and written out. The program also will write out the partial cross sections and eigenphase sums in a form suitable for plotting.

Input data records

  1. iukmll, iukmhl, icntrl, iukmat, nallu, nahlu, iprnfg, iuins, iuplt, klab

Definition of the input variables

iukmll
input unit with K or T matrices containing on low l matrix elements.
iukmhl
input unit with K or T matrices containing on high l matrix elements.
icntrl
integer, control flag
iukmat
output unit for final K matrices formed from the combined T matrices.
nallu
integer, number of partial waves to use from low l matrices. If nallu < 0 then use all partial wave found on unit iukmll
nahlu
integer, number of partial waves to use from high l matrices. If nahlu < 0 then use all partial wave found on unit iukmhl
iprnfg
integer, print flag.
iuins
input unit, contains the b_(lm) coefficients for the full point group.
iuplt
output unit for the partial cross section and eigenphase data, in a format suitable for plotting.
klab
character string (LEN = 50), label for the calculation.
