Disintegration of the deuteron by reactor antineutrinos and the axial meson exchange current effects

Abstract

Using the realistic $\mathrm{NN}$ interaction we study the influence of the axial meson exchange current effects on the cross sections and spectra in the weak neutral and charged disintegration of deuterons. In the hard pion approach we estimate these effects to be \ensuremath{\cong}8%. We suggest that an accurate experimental study of the problem may reveal the existence of the axial meson exchange current effects and the isobar configurations in nuclear physics.NUCLEAR REACTIONS $d({\overline{\ensuremath{\nu}}}_{e},{\ensuremath{\nu}}_{e}^{\ensuremath{'}})np$, (${\overline{\ensuremath{\nu}}}_{e},e$), reactor antineutrinos.
