20∼100 MeV 영역의 中性子-陽性子 산란에 관한 연구
노평식 崇田大學校 1985 論文集 Vol.15 No.1
The low energy (less than 15 Mev) formula based on the scattering length and the effective-range theory which gives us theoretical values of total cross section for neutron-proton scattering could be applied to the incident neutron energy range (laboratory-energy) from 20Mev to 100 Mev by replacing the value of the singlet effective range. The best value of the singlet effective range was found to be 1.423F rather than 2.4F and this value showed the theoretical calculations agreed well with the the experimental values of the total cross ssections for elastic N-P scatterings (less than 100 Mev).
