Abstract

Cross sections for 93Nb(n,n′)93 m Nb and 93Nb(n,2n)93 m Nb reactions were evaluated using nuclear model calculation and experimental data. The ELIESE-GNASH joint program, the Hauser-Feshbach code with preequilibrium correction, was used for calculation of cross sections to obtain consistent data set of all the cross sections and particle emission spectra. To establish reliable excitation functions for the dosimetry application, the cross sections and their covariances were evaluated from the results of the nuclear model calculation and recent experimental data using a generalized least squares program, GMA. The fission spectrum and Li(d,n) neutron spectrum averaged cross sections calculated from the evaluated cross sections were compared with the recent integral experiments. The degree of agreement for both the reactions was good.
