摘要

The cross sections for ²⁰⁹Bi(n,3n)²⁰⁷Bi, ¹⁹¹Ir(n,3n)¹⁸⁹Ir, ¹⁵¹Eu(n,3n)¹⁴⁹Eu and ¹⁸⁵Re(n,3n)¹⁸³Re reactions were measured by the activation method. The experimental results were 12.1±1.1, 64.6±6.5, 2.7±0.4 and 66.0±5.6mb at the neutron energy of 14.8±0.2MeV, respectively. The neutron flux was determined by the cross section of the ²⁷Al(n,α)²⁴Na reaction. The neutron energy in these measurements was determined by the method of cross section ratios for ⁹⁰Zr(n,2n)^89m+gZr and ⁹³Nb(n,2n)^92mNb reactions.
