Separation of Flip and Non-Flip parst of Charge Exchange np->pn at   energies Tn = 0.5 - 2.0 GeV
  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.
