Global optical model potential for A = 3 projectiles

A global optical model potential (GDP08) for 3He projectiles has been obtained by simultaneously fitting the elastic scattering data of 3He from targets of 40 AT 209 at incident energies of 30 Einc 217 MeV. Uncertainties and correlation coefficients between the global potential parameters were obtained by using the bootstrap statistical method. GDP08 was found to satisfactorily account for the elastic scattering of 3H as well, whichmakes it a global optical potential for the A = 3 nuclei. Optical model calculations using the GDP08 global potential are compared with the experimental angular distributions of differential cross sections for 3He-nucleus and 3H-nucleus scattering from different targets of 6 AT 232 at incident energies of 4 Einc 450 MeV.
