Relativistic effects in neutrino (antineutrino) disintegration of the deuteron

The cross section of neutrino disintegration of the deuteron with inclusion of relativistic corrections is calculation. The transition only to 1S0-state is taken into account, so the results are valid for reactor and meson factory energies. Comparison with earlier works is given. It is shown, that accurate choice of bound state wave function is essential for the final results. The relativistic approach developed in this work should be used as a starting point for calculations of meson exchange current corrections. (orig.)
