Modified Phase-Shift Analysis forp-He3Elastic Scattering

Abstract

The phase-shift analysis of $p$-${}_{}{}^3{}_{}{}^{}\mathrm{He}$ elastic scattering is modified by using peripheral values for the phase shifts for $l$ values corresponding to impact parameters greater than the nuclear radius. We observe a marked improvement in the weighted variance. We obtain a value of about 2.2 for the normalization of the tail of the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ wave function.
