P-violating effects in the polarization phenomena of the γ + D → N + P reaction near the threshold

Abstract

Since at the threshold the P-odd amplitude of deuteron photodisintegration (γ + D → P + N) is determined by three independent multipole amplitudes (describing the El →¹S₀, El →³S₁, and M2 →³S₁ transitions), at least three different experiments on measuring the P-odd polarization characteristics of the γ + D → P + N process are needed (provided that P-odd threshold amplitudes are known) in order to determine the multipole amplitudes. A P-odd dependence of the threshold cross section on the polarizations of the colliding γ-quantum and deuteron is established and P-odd contributions to the polarization vector of protons formed in the γ + D → P + N process are found. The P-odd characteristics are calculated in terms of P-even and P-odd threshold amplitudes.
