摘要: 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.
