Abstract

We performed the experiment of p–$^{3}$He scattering at 65 MeV by using polarized proton beams and the newly constructed polarized $^{3}$He target. The proton analyzing power $A_{y}$, the 3He analyzing power $A^{T}_{y}$, and the spin correlation coefficient $C_{yy}$ were measured. In the conference, the experimental data were compared with the rigorous numerical calculations based on various nuclear potentials. Large discrepancies between the experimental data and the calculations were found in the $A^{T}_{y}$ and the $C_{yy}$ at the backward angles.

Report

Report on "Measurement of spin correlation coefficients in p–3He scattering at 65 MeV" This short paper summarises the authors' presented work at the EFB24 conference on results of p-He-3 scattering using a polarised beam and target. The paper gives an introduction, presents experimental data compared with calculations, showing a discrepancy at backwards angles for two of the observables. An outlook for future work is then given. The paper is written clearly, and presents its results suitably. It is appropriate to publish as is in the conference proceeding
