Abstract

The proton, alpha-particle, and He+ induced X-ray emissions of Ni were measured on mono-elemental thin films in order to obtain the K-shell X-ray production cross section in the energy range of 0.7–2.0MeV for protons, 4.0–6.5MeV for alpha-particles, and 3.0–4.0MeV for He+. The proton-induced X-ray production cross section for Ni agreed well with the theoretical values, endorsing the quality of the measurements. The X-ray production cross section induced with alpha-particles is in good agreement with ECPSSR theory in the complete range of energies, while for He+ that quantity is systematically below. Kβ/Kα ratios were evaluated and compared with experimental and theoretical values.
