摘要/Abstract

摘要： 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.
