Cross-sections of 45Sc(n, 2n)44m,gSc reaction from the reaction threshold to 20 MeV

Cross sections of Sc-45(n, 2n)Sc-44m,Sc-g reactions and their isomeric cross section ratios sigma(m)/sigma(g) have been measured at three neutron energies between 13.5 and 14.8 MeV using the activation technique. The pure cross section of the ground-state was then obtained by utilizing the absolute cross section of the metastable state and analysis methods of residual nuclear decay. The monoenergetic neutron beam was produced via the H-3(d, n)He-4 reaction. The cross sections were also estimated with the TALYS-1.2 nuclear model code using different level density options, at neutron energies varying from the reaction threshold to 20 MeV. Results are also discussed and compared with some corresponding values found in the literature.
