Hi Phillipos. A correction to my last email. You have to create data files for the inelastic scattering of n on He4 in the G4NDL database and not for the elastic physics! Data for neutron elastic scattering on He4 are already present and nothing has to be changed there. More precisely copy the files G4NDL3.9/Inelastic/CrossSection/2_3_Helium G4NDL3.9/Inelastic/F23/2_3_Helium G4NDL3.9/Inelastic/F24/2_3_Helium on the files G4NDL3.9/Inelastic/CrossSection/2_4_Helium G4NDL3.9/Inelastic/F23/2_4_Helium G4NDL3.9/Inelastic/F24/2_4_Helium and change the file G4NDL3.9/Inelastic/CrossSection/2_4_Helium to have very small cross sections, Below I reproduce the G4NDL3.9/Inelastic/CrossSection/2_4_Helium that I do use in my simulations. 0 0 3 0.100000E-04 3.e-10 0.100000E+08 2.e-10 0.200000E+08 1.e-10 Let me know if it works Best regards Laurent
