对 SHIELD程序进行了部分检验 ,利用 SHIELD程序计算质子入射铅的薄靶产生的靶碎片的截面及质量分布和激发函数 ,计算结果较好地再现了实验数据 .并计算了 1 .6Ge V的质子轰击长 60 cm和直径 2 0 cm的铅靶的碎片质量分布 .
The SHIELD program was partially tested, and the SHIELD program was used to calculate the cross sections and mass distributions and excitation functions of the target fragments produced by the proton incident thin target. The experimental results are well reproduced and the calculated results of the proton Shells mass distribution of lead targets of 60 cm in length and 20 cm in diameter was bombarded.
