Measurement of alpha induced reaction cross-sections on $^{nat}$Mo with detailed covariance analysis

Abstract

In the present study we have measured the excitation functions for the nuclear reactions 100 Mo(α,n) 103 Ru, nat Mo(α,x) 97 Ru, nat Mo(α,x) 95 Ru, nat Mo(α,x) 96g Tc, nat Mo(α,x) 95g Tc and nat Mo(α,x) 94g Tc in the energy range 11-32 MeV. We have used the stacked foil activation technique followed by off-line gamma ray spectroscopy technique to measure the excitation functions. In this study we have also documented detailed uncertainty analysis for these nuclear reactions and their corresponding covariance matrix are also presented. The excitation functions are compared with the available experimental data from EXFOR data library and the theoretical prediction from TALYS nuclear reaction code. The present measurements are found to be consistent with the available experimental data.

Optical potential for incident and emitted low-energy $α$ particles. III. Non-statistical processes induced by neutrons on Zr, Nb, and Mo nuclei

“…Except for the highest energy, the (α, xn) crosssections calculated in this work using the α-particle OMP [1] agree with the most recent measured data [75,76] within their error bars [Fig. 10(b)].…”

“…The recently measured cross-sections of (α, γ) [47,48] and (α, n) [72][73][74][75][76] reactions, the former being already taken into account for RSF endorsement, are of particular interest for a customary further validation of the α-particle OMP [1], too.…”

“…10(b)], the same target nucleus was chosen as a proof-of-principle measurement in the inverse kinematics of (α, xn) inclusive cross-sections between 8.9-13.2 MeV in the center of mass [75]. Moreover, while new (α, n) cross-sections have been reported in the en- ergy range 11-32 MeV [76], too, only the lowest energy point has been considered hereafter to avoid additional PE effects within this discussion.…”
