摘要：

The M X-rays of Th and U have been produced by alpha particle bombardment in the energy range of 2.5-4.5 MeV. N6,7-->M5(M(alpha)), N6-->M4(M(beta)), N5-->M3(M(gamma)), N4-->M2 and N2-->M1 lines were selected to deduce M-subshell X-ray production cross sections. The radiative transition rates and the Coster-Kronig yields and M-subshell fluorescence yields were used to convert the X-ray production cross sections into M-subshell ionization cross sections. The deduced M-subshell ionization cross sections were compared with the ECPSSR predictions. The discrepancies of our experimental results from the theoretical calculations are discussed.
