Abstract
A global optical model potential (GDP08) for 3He pro jectile has been obtained by simultaneously
fitting the elastic scattering data of 3 He from targets of 40<=AT<=209 at incident energies between
30<=Einc<=217 MeV. Uncertainties and correlation coefficients between the global potential param-
eters were obtained by using the bootstrap statistical method. GDP08 was found to satisfactorily
account for the elastic scattering of the 3H as well, which makes 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 the 3He- and 3H-nucleus
scattering from different targets of 6<=AT<=232 at incident energies between 4<=Einc<=450
MeV. The optical potential for the doubly-magic nucleus 40 Ca, the low-energy correction to the real
potential for nuclei with 58<=AT<=120 at Einc < 30 MeV, the comparison with double-folding
model calculations and the CH89 potential, and the spin-orbit potential parameters are discussed.
