Kr L X-ray and Au M X-ray emission for 1.5 MeV–3.9 MeV Kr13+ ions impacting on an Au target

doi:10.1088/1674-1056/22/10/103403

Abstract Kr L X-ray and Au M X-ray emission for Kr¹³⁺ ions with energies of 1.5 MeV and 3.9 MeV impacting on an Au target are investigated at heavy ion research facility in Lanzhou (HIRFL). The L-shell X-ray yield per ion of Kr is measured as a function of incident energy. In addition, Kr L X-ray production cross section is extracted from the yield and compared with the result obtained from the classical binary-encounter approximation (BEA) model. Furthermore, the intensity ratio of the Au M_β3 to M_α1 X-ray is investigated as a function of incident energy.

Keywords: X-ray yield per ion X-ray production cross section intensity ratio
