The $A_y$-Problem in Refined Resonating Group Model calculations for ($p{-}^3\mathrm{He}$) Scattering

Abstract

We report on a microscopic Refined Resonating Group Model (RRGM) calculation of scattering of $p$ off ${}^3\mathrm{He}$ employing the Argonne-$v_{14}$ and the Bonn nucleon-nucleon potentials without three-nucleon forces at low energies up to 30 MeV. The calculated phase-shifts verify the well-known proton analyzing power $A_y$-problem. We demonstrate that with corrected ${}^3{P}_2$ phase-shifts experimental differential cross-section and analyzing power data can be explained.
