Global optical model potential for A = 3 projectiles

Global optical model potential for A = 3 projectiles A global optical model potential (GDP08) for He 3 projectiles has been obtained by simultaneously fitting the elastic scattering data of He 3 from targets of 40 ⩽ A T ⩽ 209 at incident energies of 30 ⩽ E inc ⩽ 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 H 3 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 He 3 -nucleus and H 3 -nucleus scattering from different targets of 6 ⩽ A T ⩽ 232 at incident energies of 4 ⩽ E inc ⩽ 450 MeV. The optical potential for the doubly-magic nucleus Ca 40 , the low-energy correction to the real potential for nuclei with 58 ≲ A T ≲ 120 at E inc < 30 MeV, the comparison with double-folding model calculations and the CH89 potential, and the spin-orbit potential parameters are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review C American Physical Society (APS)

Abstract

A global optical model potential (GDP08) for He 3 projectiles has been obtained by simultaneously fitting the elastic scattering data of He 3 from targets of 40 ⩽ A T ⩽ 209 at incident energies of 30 ⩽ E inc ⩽ 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 H 3 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 He 3 -nucleus and H 3 -nucleus scattering from different targets of 6 ⩽ A T ⩽ 232 at incident energies of 4 ⩽ E inc ⩽ 450 MeV. The optical potential for the doubly-magic nucleus Ca 40 , the low-energy correction to the real potential for nuclei with 58 ≲ A T ≲ 120 at E inc < 30 MeV, the comparison with double-folding model calculations and the CH89 potential, and the spin-orbit potential parameters are discussed.
