PLASMON ipl 

This card runs feff with the multiple-pole self energy.

The values of the argument ipl correspond to the following: 0: run regular FEFF but print out the self energy; 1: run multiple pole self energy without renormalization; 2: run multiple pole self energy with renormalization.

It takes as input `exc.dat' which can be formed in the following way:

  1. Calculate or measure the energy loss spectrum epsilon-inverse
  2. Use the formula detailed in `EpsInvFormula.ps' to calculate omegai and fi. Now write three columns in `exc.dat', omegai,

gammai, and fi. gammai is irrelevant at this time. Units should be eV.

The output file `sigma.dat' contains the self energy and the renormalization constant (at the interstitial radius) as a function of photoelectron energy in eV.
