Ionisation of L subshells of heavy atoms by deuteron collision

Li subshell ionisation cross sections for 1.2-3.0 MeV deuteron impact on thin targets of W, Au, Pb and Bi have been measured experimentally. Measurements were made with the Birmingham University's 3MV Dynamitron accelerator and the cross sections were deduced from the emitted L X-rays. These cross sections and their ratios have been compared graphically with the ECPSSR and RHSCA models. The ECPSSR model underestimates the measured L2 subshell cross sections but shows very good agreement with the L3 subshell values. The RHSCA theory in general exhibits good agreement with the measured cross sections for the L1 and L2 subshells but overestimates the L3 cross sections by up to 60%. (orig.)
