摘要
本文报告了E_■=13.50—14.73MeV中子能区用活化法以^(27)Al(n,2)^(24)Na截面为中子注量标准测得的^(107)Ag(n,2n)^(106m)Ag的反应截面.在E_■=13.50,13.60,13.90,14.10,14.35,和14.73MeV处的截面分别为469±22,480±22,503±24,538±25,555±25和572±26mb.在文中还列举了一些国外已发表的截面数据以作比较.中子能量用铌锆活度比法测定.
The cross section for ^(107)Ag(n, 2n) ^(106m)Ag has been measured by using the activation method relative to the cross section of ^(27)Al(n, α)^(24)Na in the neutron energy range of 13.50—14.73 MeV. The values of 469±22, 480±22, 503±24, 538±25, 555±25, 572±26 mb were obtained at the 13.50, 13.60, 13.90, 14.10, 14.35 and 14.73 MeV neutron energy, respectively. The results are compared with the published data. The neutron energies were determined by activity ratios of Nb and Zr foils.
