| 摘 要： | 运用密耦近似方法计算了能量在100meV下He原子和基态HF分子碰撞的态-态转动激发截面和碰撞能量分别在100meV,150meV,200meV,250meV下的总微分截面和总分波截面;总结了该碰撞体系散射截面的变化规律。系统研究表明:在低能散射时,弹性散射主要发生在小角部分,非弹性转动激发主要发生在大角部分。

| Abstract: | State-state rotational-excitation cross sections,total different scattering cross sections and total partial wave scattering cross sections are calculated for He-HF system by employing the accepted exact close-coupling approximation method at collision energy of 100,150,200 and 250 meV cases,respectively.Then the chancing regularities of collision cross sections are summed up.Systemic investigations shows that elastic scattering takes place mainly at small scattering angle while inelastic rotational-excitation takes place at large scattering angle at low-energy scattering for He-HF system. |
