【Abstract】 Abstract In low projectile energy region,the alignment of L₃ vacancy state in Au andthe 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 ap- proximation （PWBA） and taking into account the coulomb deflection effect, the align-ment was calculated . It is shown that the present calculated results are closer to the experimental data. The alignment behavior of L-3 vacanct state in Au is furtherlydiscussed.更多还原
