Analysis of average primary gamma-transition intensities and cross sections of the113Cd(n, ?) reaction

Abstract

A combined analysis of the available data on the primaryγ-ray intensities from the113Cd(n, γ) reaction atEn=1.9 and 24.3 keV neutron energies together with the data on113Cd neutron capture cross sections in theEn=3–200 keV energy region was carried out. The neutron strength functions were determined asSn0=(0.260±0.073) 10−4 and Sn1=(5.06±0.67) 10−4. No spin-orbit splitting of thep-wave neutron strength function was found. The energy dependence of theE 1 radiative strength function {ie147-01} was fitted by the Kadmenski-Furman model somewhat better than by a standard Lorentzian. TheM 1 giant resonance parameters were obtained as EGM 1=8.8±1.6 MeV and ΓGM 1= 4.7±2.6 MeV. The neutron capture cross section of113Cd from its isomeric state ({ie147-02}=11/2−, E1m=263.7 keV) was calculated.
