| 摘 要： | 作者运用密耦近似方法,计算了能量在64.0meV下,He原子和基态N2分子碰撞的态-态转动激发微分截面和入射能量分别在27.3meV,40.0meV,64.0meV和80.0meV下的弹性、非弹性和总微分截面;总结了该碰撞体系微分散射截面的变化规律.研究表明:在低能散射时,弹性散射主要发生在小角部分,转动激发非弹性散射主要发生在大角部分. |

| Abstract: | The state-to-state differential cross sections of rotational excitation at incident energy 64.0meV and elastic,inelastic and total differential 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 differential scattering cross sections are summed up.It shows by investigation that elastic scattering takes place mainly at ... |
| Keywords: | close-coupling approximation rotational excitation scattering cross section |
