Abstract

New results of the Delta-Sigma experiment on measuring the R dp ratio made it possible to separate flip and nonflip parts of the differential cross section of the np → pn reaction at zero angle using the Dean formula. Phase-shift-analysis (PSA) solutions for elastic np → np scattering are transformed into a np → pn charge-exchange representation using unitary transformations, which testifies to the good agreement of the theoretical and experimental results.
