TL;DR

This paper uses new experimental data to separate flip and non-flip components of the charge exchange process np->pn at energies between 0.5 and 2.0 GeV, enhancing understanding of nucleon interactions.

Contribution

It introduces a method to distinguish flip and non-flip parts of the charge exchange cross section using the Dean formula and new Delta-Sigma data, improving analysis accuracy.

Findings

Successful separation of flip and non-flip parts at zero angle.

Good agreement between PSA solutions and charge exchange data.

Enhanced understanding of nucleon charge exchange mechanisms.

Abstract

The new Delta-Sigma experimental data on the ratio $R_{dp}$ allowed separating the Flip and Non-Flip parts of the differential cross section of $np\to pn$ charge exchange process at the zero angle by the Dean formula. The PSA solutions for the $np\to np$ elastic scattering are transformed to the $np\to pn$ charge exchange representation using unitary transition, and good agreement is obtain.
