Abstract The continuum radiation emitted after the proton bombardment of a solid or gaseous target can be described mainly by three mechanisms: the secondary electron bremsstrahlung (SEB), the quasi-free electron bremsstrahlung (QFEB) and the atomic bremsstrahlung (AB). Each background mechanism exhibits a different relative contribution in the PIXE continuum according to the projectile energy, the …

Abstract The forward (γF) and backward (γB) electron emission yields have been measured for protons incident on thin carbon foils for incident energies between 2 and 7 MeV as a function of the target thickness. Comparisons with theoretical results obtained by Monte Carlo simulations are presented. In particular, the Meckbach factor Rγ = γF/γB is discussed. C. Potiriadis, A. Clouvas, …

Abstract The forward and backward electron emission yields γF and γB have been calculated by Monte Carlo simulation for protons (H+) and hydrogen atoms (H0) (with energies between 25 keV and 5 MeV) incident on thin amorphous carbon foils. Direct electron excitations by the incident projectiles as well as electron excitations resulting from charge exchange processes undergone by H+ or H0 have been …
