Investigation of pairing effect by using the new evaluated empirical systematic for 14-15 MeV neutron reaction cross sections

Recently, especially having around threshold energy more new and sensitivecross section experimental measurements for neutron induced have been made.Precise cross section data measurement of neutron around 14-15 MeV energyand particle emission spectra are very important for understanding the nuclearforce, nuclear structure and refinement nuclear models. Tel et al. havesuggested using these new experimental data to reproduce a new empiricalformula of the cross-sections of the (n,p) reactions with dependent onasymmetry parameter s = N-Z/A and nuclear shell model. Betak et al. have112-124found agreement with odd-A nucleus in latest experiment for Sn thintarget. Tel et al have obtained new appropriate coefficient by modifying thewith depend on the pairing effect formula for (n,2n) and (n,α) reactions.In this study, we discussed odd-even effect and basic nucleon-nucleon effect withthe nuclear shell model considering new experimental data results and newcross sections formulas (n,p), (n,2n), (n,α) and (n,t) reactions developed by Telet al
