Effect of the Incident Energy on the Observables of Proton Elastic Scattering on Halo Nucleus

  • The proton elastic scatterings on 14Be, 16O and 12C at the intermediate incident energies of 200, 400 and 800MeV, are investigated within the relativistic impulse approximation (RIA). The effect of the incident energy on three observables, the differential cross section, the analyzing power and the spin rotation function, is discussed. It is shown that in the region of small scattering angle, the halo neutron effect on the observables exhibits an unchanged tendency with the variation of the incident energy of proton in the intermediate energy region.

Abstract: The proton elastic scatterings on 14Be, 16O and 12C at the intermediate incident energies of 200, 400 and 800MeV, are investigated within the relativistic impulse approximation (RIA). The effect of the incident energy on three observables, the differential cross section, the analyzing power and the spin rotation function, is discussed. It is shown that in the region of small scattering angle, the halo neutron effect on the observables exhibits an unchanged tendency with the variation of the incident energy of proton in the intermediate energy region.
