K-K electron transfer and K-ionization in fast ion collisions with adenine and water using KLL Auger electron technique

Abstract

In this report, we present a study of K-shell ionization, state selective K-to-K electron capture cross sections from C and N atoms in the adenine and other gas molecules using K-LL Auger electron technique, which is applied for first time. Energy dependence of K-ionization and K-K electron capture has also been measured. The e-transfer cross section is found to be substantial compared to the K-ionization. Total δ KK and δKI for the entire molecule was deduced.
