Abstract:

A dispersion method is propsed to calculate the parameters characterizing the P-odd part of the nucleon-nucleon amplitute. These parameters are expressed in terms of the NN-scattering phase-shifts and the meson-nucleon coupling constants. Under the usual assumptions concerning the magnitudes of the mentioned coupling constants the values of the circular polarization P and the asymmetry

\alpha

of the

\gamma

-emission with respect to the neutron spin inthe reaction

n+p\to d +\gamma

are

|P|= 1.81 \times 10^{-8}

,

|\alpha| = 4.10^{-9}
