Description

The utilization of different heavy ion beam analytical techniques such as heavy Particle Induced X-ray Emission, heavy ion Elastic Recoil Detection Analysis (ERDA), etc. is dependent on availability of accurate and reliable heavy ion-matter interaction database. Adding new experimental data of heavy ion induced X-ray production cross sections in elemental films to expand the existing global database of basic ion-atom interaction is of great importance.

In this work, L-shell X-ray production cross sections in bismuth induced by 7-35 MeV 35Clq+ and 4-12 MeV 12Cq+ ions have been measured. Multiple ionization effect on the ions is discussed. Experimental results are compared with ECPSSR, ECPSSR+EC and ECPSSR-UA theoretical predictions. There is fair agreement between the data, ECPSSR+EC and ECPSSR models for 12Cq+ ions while the ECPSSR+UA calculations overestimate experiment data. ECPSSR+EC calculations show good agreement with experiment for 35Clq+ ions while the ECPSSR prediction underestimates the experimental results.
