- Abstract
We present the measured spin correlation coefficient C y , y for p- 3 He 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 3 He target. Proton beams were injected to the target, and scattered protons were detected by using E- Δ E 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.
