Optical model potential of A=3 projectiles for 1 p-shell nuclei

A set of global optical potential parameters describing the A = 3 particles (He-3 and H-3) elastic scattering' from 1p-shell nuclei, HT1p, is obtained by simultaneously fitting 118 sets of experimental data of He-3 and H-3 elastic scattering from Be-9, B-10, B-11, C-12, C-13, C-14, N-14, N-15, O-16, O-17, and O-18 with incident energies from 4 <= E <= 118.5 MeV and 24 sets of elastic scattering data with the Li-6 and Li-7 targets from 3 <= E <= 44 MeV. HT1p is found to be superior to GDP08 [D. Y. Pang, P. Roussel-Chomaz, H. Savajols, R. L. Varner, and R. Wolski, Phys. Rev. C 79, 024615 (2009)], which is a systematic potential designed for the heavy-target region, in the reproduction of the angular distributions of elastic scattering cross sections of 3He and 3H from 1p-shell nuclei at energies below 100 MeV. At energies above 100 MeV, GDP08 is found to be better than HT1p.
