The isomeric cross section ratio {sigma}{sub m}/{sigma}{sub g} for the reaction {sup 45}Sc(n,2n) {sup 44}Sc{sup m,g} was measured in the neutron energy range of 13.6{endash}14.9 MeV for six different neutron energies. The neutrons were produced by the {sup 3}H(d,n){sup 4}He reaction utilizing a SAMES T-400 neutron generator. Isomeric cross section ratios were determined by applying the method of least squares to the time behavior of the ground-state decay of isomeric pair. The absolute cross section for the formation of the metastable state was measured by the usual activation technique. The ground-state cross section was then obtained by using the absolute cross section of the metastable state and isomeric cross section ratio for each neutron energy. Experimental cross section values and isomeric cross section ratios were compared with those obtained by a statistical model calculation. {copyright} {ital 1997} {ital The American Physical Society}
