The problem of the unambiguity of phase-shift analysis I

Abstract

The new results of phase-shift analysis at energies of 23·1 and 18·2 MeV are discussed. Two and three solutions remain at these energies respectively. The measurements of triple n-p scattering parameters are necessary for obtaining the unambiguity of the solutions. It is shown that the Berkeley p-p polarization data at 19·7 MeV are in disagreement with other results.
