70MeV质子束轰击^(72)Ge靶放射性核产生率的计算

CALCULATIONS OF THE PRODUCTION RATE OF RADIOACTIVE NUCLEAR BEAM INDUCED BY 70 MeV PROTONS ON 72 Ge TARGET

在理论计算的有关截面能相当好地符合实验数据的前提下，用核反应模型ＳＰＥＣ程序计算了７０ＭｅＶ质子束轰击７２Ｇｅ及其化合物Ｚｒ５Ｇｅ３厚靶所产生的几种主要放射性核的产生率。

Under the condition of the calculated relative cross sections is in good agreement with the experimental data,the production rate(s -1 ·μA -1 ) of the main radioactive nuclei induced by 70 MeV protons on 72 Ge and its compound Zr 5Ge 3 targets are calculated by nuclear reaction model code SPEC.The calculated production rates of 72 As and 71 As are higher 2—3 times than the evaluated values abroad.
