Nucleon-energy correlations in νd-->νnp

The nucleon-energy correlation σ (K₁,K₂), where K₁ and K₂ are the kinetic energies of the outgoing nucleons, is studied in the weak neutral disintegration of the deuteron, ν+d-->ν+n+p. The studies are made in all five (S, P, T, A, and V) variants of the neutral-current weak-interaction Lagrangian. The study in the region of low kinetic energies of the nucleons provides means to distinguish between the axial-vector and tensor couplings.
