Abstract

We present the measured spin correlation coefficient C_y,y for p-³He elastic scattering at 100 MeV at the angles θ_c.m.=46.9^∘–149.2^∘ in the center of mass system. The experiment was performed using a 100 MeV polarized proton beam in conjunction with the polarized ³He target. Proton beams were injected to the target, and scattered protons were detected by using E-ΔE detectors which consisted of plastic and NaI(Tl) scintillators. The data are compared with rigorous numerical calculations based on realistic NN potentials as well as with the Δ-isobar excitation. The obtained results indicate that the C_y,y expands the knowledge of the nuclear interactions with Δ-isobar or those including 3NFs that are masked in nucleon-deuteron elastic scattering.
