THE CROSS SECTION MEASUREMENT FOR THE ^(62)Ni (n, α) ^(59)Fe REACTION

本文报告了在E_n=13.6—14.8MeV中子能区用活化法以^(27)Al(n,α)^(24)Na截面为中子注量标准测得的^(62)Ni(n,α)^(59)Fe的反应截面.在E_n为13.64,13.79,14.00,14.05,14.33,14.60和14.80MeV处的截面分别为17.4±1.1,19.5±1.5,21.9±1.9,22.4±1.6,25.4±1.4,26.1±1.1和26.0±1.1mb.在文章中还列举了所能收集到的一些作者的数据以作比较.中子能量是用铌锆截面比法测定的.

The cross sections for ^(62)Ni(n, α)^(59)Fe have been measured by using the activation method relative to the cross sections of ^(27)Al(n,α)^(24)Na in the neutron energy range of 13.6-14.8 MeV. The values of 17.4±1.1, 19.5±1.5, 21.9±1.9, 22.4±1.6, 25.4±1.4, 26.1±1.1, and 26.0±1.1mb were obtained at the 13.64, 13.79, 14.00, 14.05, 14.33, 14.60, and 14.80 MeV neutron energies, respectively. The results are compared with the published and to be published data. The neutron energies were determined by the method of cross section ratios for the reactions ^(9(?))Zr(n, 2n)^(89m+g)Zr by ^(93)Nb(n, 2n) ^(92m)Nb.
