摘要:
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 0.7-2.0 MeV for protons, 4.0-6.5 MeV for alpha-particles, and 3.0-4.0 MeV 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. K-beta/K-alpha, ratios were evaluated and compared with experimental and theoretical values. (C) 2015 Elsevier B.V. All rights reserved.
