| 摘 要： | 运用密耦近似方法计算了He原子入射能量分别为27.3m eV、40.0m eV、64.0m eV和80.0m eV与基态N2分子碰撞的弹性、非弹性和总分波截面;并总结了该碰撞体系分波截面的变化规律。研究表明:尾部效应仅在低激发态中产生,高激发态不产生尾部效应。

| Abstract: | The elastic,inelastic and total partial wave cross sections are calculated for He atom collision with ground state N_2 molecule by employing accepted exact close-coupling approximation method at incident energy of 27.3,40.0,64.0 and 80.0meV,respectively.Then the changing regularities of partial wave scattering cross sections are summed up for He-N_2 collision system.The research shows that the tail effect emerges only in lower exciting states,there isn't tail effect in higher exciting states. |

| Keywords: | close-coupling approximation rotational excitation partial wave cross section scattering cross section. |
