Our High Energy Extension model for Quantemol-N software is based on Static Exchange model (SE) for 20-50 eV energy range and Spherically Complex Optical Potential (SCOP) method for energies 50-10000 eV. Quantemol-N now combines low energy electron solution obtained from R-matrix (up to 20 eV) with high energy solution from SE and SCOP to provide users with a full range of energies.
Our team has run a set of tests to compare the experimental data:
