ECPSSR theory is one of most successful theories in ion-atomic collision which is widely used to calculate the inner shell ionization cross sections and X-ray production cross sections in ion-atom collisions.

This paper presents the measurement results of absolute cross-sections of ion-atom collision in detail.

State-selective differential cross sections in ion-atom collisions studied by reaction window theory;

Based on the molecular Coulombic over barrier model for description of slow ion-atom collisions, the reaction window theory related to projectile velocity is presented briefly.
