✦ Synopsis

L-subshell ionization induced by 1.0-8.5 MeV 4He2' was measured experimentally for a thin target of Yb using simultaneous acquisition of PIXE and RBS yields. The data were compared with the theoretical predictions of the ECPSSR theory and its extensions known as the ECPSSR-IS and ECPSSR-IS-UA theories. Good agreement was found for the and at energies higher than about 5 MeV, whereas a fair agreement with the theory L 1 -L 3 -subshells was observed for the Possible reasons for the discrepancies are discussed in the framework of vacancy L 2 -subshells. transfer from the to the and 1998 John Wiley & Sons, Ltd.
