Determination of the difference between the mean and the most probable energy loss of low-energy proton beams traversing thin solid foils

Autor: N. R. Arista, E.A. Figueroa, G. H. Lantschner, J. C. Eckardt

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 256:126-130

Precise determinations of the energy loss of ion beams in solid targets in the low-energy range (typically a few keV/u) using the transmission technique, require, among other things, a fine analysis of the energy distributions of the transmitted ion
