| Abstract: | In low projectile energy region, the alignment of L3 vacancy state in Au and the projectile energy dependence of alignment were measured for several kinds of ions and Au collision systems by a simple method. Using the plane-wave Born approximation (PWBA) and taking into account the coulomb deflection effect, the alignment was calculated. It is shown that the present calculated results are closer to the experimental data. The alignment behavior of L3 vacancy state in Au is furtherly discussed. |
