Study of interaction potential and differential scattering cross section for he - n 2碰撞体系相互作用势及微分散射截面的研究
Following is our main work and important conclusions : ( 1 ) the question of energy spectrum hardening . we used the klein - nishina ' s differential scatter formula , meanwhile utilize the thaler progression to spread out , and neglected the high - power , and then we deduced a theoretical formula of correction of energy spectrum hardening 其主要工作和结论如下: ( 1 )对x射线能谱硬化问题,把klein - nishina微分散射方程,利用泰勒级数展开,在忽略高次项的情形下,近似地推导出了能谱硬化修正公式。
