[en] Due to the quasi-monoenergetic behavior of neutron sources, neutron induced reaction cross sections are usually measured as spectrum averaged in activation analysis methods. The established neutron sources having an energy spread higher than 2%, limits the cross section measurements in a finite energy bin. However such limitations can be overcome, up to some extent, using Fredholm integral based unfolding approach. The feasibility analysis of single projection based excitation function unfolding controlled by monitor, using ¹¹⁵In(n,n')¹¹⁵mIn reaction shows the unfolded excitation function is in a good agreement with ENDF/B-VIII.0 benchmarked data. The unfolded cross section for ⁴⁷Ti(n,p)⁴⁷Sc and ⁴⁸Ti(n,*)⁴⁷Sc channels of residual yield, monitor cross sections and Likelihood estimates, propagated through the covariance matrices are significantly reasonable to the unfolded data points. Similarly the unfolded excitation function for ⁴⁷Ti(n,p)⁴⁷Sc, ⁴⁸Ti(n,*)⁴⁷Sc are also very well matches with theoretical as well as the previously reported experimental data, measured using enriched samples
