Some of the energy intended for the photon is drained off by the recoiling atom . 原来给予光子的能量有一部分为反冲原子所消耗。
2.
The recoil atoms with high energy and the residual nuclear are dealt with in a strict way 计算中对核散射产生的次级粒子及核反应剩余核都进行了跟踪。
3.
The measured spectra were transformed to the concentration profiling of the recoil atoms by using the knowledge of the rutherford cross section and the stopping power of the projectile and the recoils in the materials 利用卢瑟福散射截面和离子在靶材料中的阻止本领，编制程序将能谱转换成元素的深度分布。从而实现高精度的深度分辨测量。
