It is pointed out that contribution of the πNN processes to the structure functions of the nucleon should be calculated by taking the recoil nucleon as a physical nucleon.
指出在计算πNN过程对核子结构函数的贡献时 ,将反冲核子视为物理核子更为合理 。
The methods to calculate the energy spectra of all kinds of emitting light particles and recoil nuclei for multilevel particle emission in medium energy region(≤250?MeV), comparison of the efficiency between this method and the traditional one and two calculated examples are given.
给出了在中能区(≤250MeV)多次粒子发射过程中计算各种出射轻粒子及各种反冲核之能谱的方法,指出它的计算效率远高于(两个数量级以上)传统方法,并给出了两个算例。
