ION-ATOM/NEON – Calculation of ionization cross sections by fast ion impact for neutral target atoms ranging from lithium to neon Original Research Article

The program presented calculates the total cross sections, and the electron energy spectra of the singly and doubly differential cross sections for the single target ionization of neutral atoms ranging from lithium up to and including neon. The code is applicable for the case of both high and low Z projectile impact in fast ion-atom collisions. The theoretical descriptions provided for the program user are based on two quantum mechanical models which have proved to be very successful in the study of ionization in ion-atom collisions. These are the continuum-distorted-wave (CDW) and continuum-distorted-wave eikonal-initial-state (CDW-EIS) approximations respectively.
