摘　　要：用CCSD(T)/aug-cc-pV5Z+bf(3s3p2d1f1g)方法,计算He-AlH复合物体系的刚性转动模型相互作用势,使用密耦方法计算了He原子低能入射时与基态AlH分子碰撞的积分截面。计算结果表明:He-AlH碰撞体系,jα=0到jβ=1跃迁的转动激发态—态积分截面,对于非弹性积分截面具有非常重要的作用。The interaction potential of Rigid rotation model of He-AlH complex system has been calculated with CCSD（T）/aug-cc-pV5Z ＋bf（3s3p2d1f1g） method and the integral cross section for collsion between the ground state of AlH molecules and helium atoms in low-energy incidence has been calculated with close-coupling method.The rotational excited state ofjα =0→jβ =1 transition of HeAlH collision system-the integral cross section of it makes a great contribution to the inelastic integral cross section.
