本文叙述１４．２±０．１ＭｅＶ中子能量的１３７Ｂａ（ｎ，ｐ）１３７Ｃｓ、１３６Ｂａ（ｎ，ｐ）１３６Ｃｓ、１３４Ｂａ（ｎ，ｐ）１３４Ｃｓ、１３２Ｂａ（ｎ，ｐ）１３２Ｃｓ、134Ｂａ（ｎ，２ｎ）１３３Ｂａ和１３２Ｂａ（ｎ，２ｎ）１３１Ｂａ等反应截面的测量，测量方法采用以５４Ｆｅ（ｎ，ｐ）５４Ｍｎ和５４Ｆｅ（ｎ，ａ）５１Ｃｒ反应为标准截面的相对活化法，并用现有的数据对本结果进行了比较． The cross sections of the 137Ba (n, p) 137Cs, 136Ba (n, p)136Cs, 134Ba (n, p ) 134Cs, 132Ba (n, p) 132Cs, 134Ba(n, 2n) 133Ba and 132Ba(n, 2n ) 131Ba reactions have been measured by using the activation method relative the cross sections of 54Fe(n, p ) 54Mn and 54Fe(n,a)51Cr reactions at the neutron energy of 14. 2 ±0. 1MeV. The results obtained are compared with the data on hand.
