The cross sections for the 46Ti(n, t)44mSc and 46Ti(n, t)44gSc reactions induced by neutrons around 14 MeV

Highlights: • The cross sections of the ⁴⁶Ti(n, t)^44mSc and ⁴⁶Ti(n, t)^44gSc reactions were obtained around neutron energy of 14 MeV. • The pure cross sections of the ⁴⁶Ti(n, t)^44gSc reaction were measured for the first time around neutron energy of 14 MeV. • The results are expected to help in new evaluations of the 14 MeV neutron cross sections. The cross-section values of the ⁴⁶Ti(n, t)^44mSc reaction have been measured around the neutron energy of 14 MeV using the activation cum γ-ray spectrometric technique and previously developed formula used to calculate the cross-section value of the excited state with the characteristic γ-ray activity of the ground state. The pure cross-section values of the ⁴⁶Ti(n, t)^44gSc reaction have also been obtained around the neutron energy of 14 MeV after subtracting the contribution of the excited state γ-ray activity from the ground state γ-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 ⁴⁶Ti(n, t)^44mSc reaction are much higher and those of the ⁴⁶Ti(n, t)^44gSc 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.
