^(63)Cu(n,α)^(60)Co反应截面测量

THE CROSS SECTION MEASUREMENT FOR THE ^(63)Cu(n,α)^(60)Co REACTION

本文报告了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^(63)Cu(n,α)^(60)Co的反应截面.在中子能量为13.64,13.79,14.03,14.33,14.60和14.80MeV的截面值分别为58.3±3.1,56.3±2.4,53.4±2.0,50.8±1.9,48.4±1.7和47.4±1.7mb.在文中还列举了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 ^(63)Cu(n,α)^(60)Co 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 58.3±3.1, 56.3±2.4, 53.4±2.0, 50.8±1.9, 48.4±1.7, 47.4±1.7mb, were obtained at the 13.64, 13.79, 14.03, 14.33, 14.60, and 14.80 MeV neutron energies, respectively. The results are compared with the published data. The neutron energies were determined by activity ratios of Nb and Zr foils.
