Elastic recoil detection analysis

This work briefly describes the basic principle of Elastic Recoil Detection Analysis. From a theoretical analysis of the physical process, we discuss the choice of the best experimental configuration for solid surface examination and particularly the advantages of the transmission geometry. Then, we propose a new calculation procedure for the collision cross section1H(4He,4He)1 H between 0.5 and 8 MeV helium ions energy, and finally we analyze in more detail the cross section results in the low energy range (1 to 2.5 MeV).
