Investigation of the Coulomb-deflection effect on the Lsub(3)-subshell alignment and on the L-subshell ionization cross sections

The angular distribution of the Lsub(l) x-ray line of gold ionized by 0.3 MeV proton and 0.4-0.66 MeV deuteron beams was measured. For deuteron impact the absolute value of the deduced alignment parameter was found to be larger than the earlier results for proton and helium projectiles of the same velocities, and at low velocities the alignment shows a projectile atomic number dependence. The ratios of the L-subshell ionization cross section for Sm, Er, and Au by 0.2 MeV/u proton and deuteron impact and those for Au by 0.3 MeV/u proton and deuteron impact are also reported. The Coulomb-deflection factor deduced from these data was compared with different types of Coulomb-deflection factors, and it was found to be in good agreement with the data of the literature.
