摘要：

The cross-section values of the Ti-46(n, t)Sc-44m reaction have been measured around the neutron energy of 14 MeV using the activation cum gamma-ray spectrometric technique and previously developed formula used to calculate the cross-section value of the excited state with the characteristic gamma-ray activity of the ground state. The pure cross-section values of the Ti-46(n, t)Sc-44g reaction have also been obtained around the neutron energy of 14 MeV after subtracting the contribution of the excited state gamma-ray activity from the ground state gamma-ray activity. The present results are compared with the experimental data from literature and with the calculated values based on the empirical and semi-empirical formulas. It was observed that the cross-section values of the Ti-46(n, t)Sc-44m reaction are much higher and those of the Ti-46(n, t)Sc-44s reaction are in good agreement with the literature data within uncertainties as well as with the calculated values based on the even-even and odd-even fitted semi-empirical formula.
