摘　　要：由Ｎｅ－Ｈ＿２相互作用势表面（ＰＥＳ）导出质心坐标下Ｎｅ－Ｄ＿２、Ｎｅ－ＨＤ体系ＰＥＳ．采用ＩＯＳＡ方法分别计算出三个不同碰撞体系的积分、微分散射截面，并对其同位素效应进行了分析．We report integral and differential crose sections for elastic and rotationally inelastic He-H_2(D_2 ,HD)coflisions.The interaction potential surfaces of Ne-D_2 (HD)are constructed empIoying thatof Ne-H_2. Pronounced diffraction effects are observed in the low angeI total and elastic differential crosesections. The widths of those oscillations in elastic transition are 5°,6°,7°respectively. The effectsof isotopic substitution are also discussed in integral cross sections.
