冲量近似 meaning in English
impulse approximation
Examples
- Imev and the data in which the energy respectively is 166mev 139mev , 104mev , 90mev . on the basis of two wave functions and two optical potentials above mentioned , we have investigated a serie s of knockout reactions : through the comparing of two wave functions and two optical potentials , we find that two a cluster relative vave functions which contribute to the energy sharing results of the reaction sections are very well , especially for the ; that the received spectroscopic factors used vfm ( r ) are better than that used ; that the former not only suits to the elastic scatterings but also to the knockout reactions ; that the a cluster of knockout reactions are its local behaviors of surface . and we further testify that the distorted influences are not neglected if the incidence energies are not very high , but can be used the plane wave impulse approximate method and neglect the effects of the distorted influences if the incident energies are high enough
在利用上述的两种束缚态波函数和两种光学势的基础上，我们研究了一系列的敲出反应：通过对比两种束缚态波函数和光学势，我们得到的结论是：两种束缚态波函数和光学势对反应截面的能量分配谱的贡献都比较好，但尤以波函数_ ( li ) ( r )为佳；光学势v _ ( clu ) + ( r )得到的光谱因子比用woods - saxon势v _ ( ws ) ( r )的结果要好，它不仅能适用于弹性散射，且对敲出反应也能得出比较好的结果；集团的敲出反应是集团表面局域性的表现：在中低能的入射条件下，扭曲效应不能忽略，但入射能量较高时，扭曲效应影响较小，可以用平面波冲量近似的方法。
