Total (p,n) reaction cross section study on ⁵¹V over the incident energy range 1.56 to 5.53 MeV

Abstract

The total (p, n) reaction cross section for⁵¹V has been measured as a function of proton energy in the energy range 1.56 to 5.53 MeV with thick and thin targets. The fluctuations in the fine resolution excitation functions were analysed, to extract <Γ>, the coherence width. The thick target excitation function suitably averaged over appropriate energy intervals has been compared with the optical model, Hauser-Feshbach and Hauser-Feshbach-Moldauer calculations. The strong isobaric analog resonance at E _p~2.340 has been shape analysed to extract the proton width Γ p , the spreading with W and the spectroscopic factor.
