摘　　要：本文报告了En～14MeV中子以^(27)Al(n,a)^(24)Na或^(93)Nb(n,2n)^(92m)Nb反应截面为中子注量标准测得的^(92)Mo(n,d~*)^(91m)Nb,^(106)Cd(n,d~*)^(105)Ag;^(54)Fe(n,t)^(25m+g)Mn,^(58)Ni(n,t)^(56)Co;^(51)V(n,n'a)^(47)Sc和^(92)Mo(n,n'a)^(88)Zr的反应截面。文中还列举了能收集蓟的数据以作比较,中子能量是用铌锆截面比法测定的。Cross sections for some (n,d~*), (n,t) and (n, n' α) reactions have been measured by using the activation method relative to cross sections of ^(27)Al(n,, a) ^(24)Na or ^(93)Nb(n, 2n) ^(92m)Nb reactions in neutron energies around 14 MeV. In this paper some of the published cross section data have also been listed and compared with our results. The neutron energies were determined by the method of cross section ratios for the reactions of ^(90)Zr (n,2n)^(89m+g) Zr and ^(93)Nb(n,2n) ^(92m)Nb
