Matter can enhance neutrino oscillations (increase the mixing parameter sin/sup 2/ 2theta/sub m/). For small mixing angles in vacuum the enhancement displays a resonance behavior in the neutrino energies or the density of the medium. This resonance effect is important for solar neutrinos in a wide range of oscillation parameters ..delta..m/sup 2/ = 10/sup -4/--10/sup -8/ eV/sup 2/ and sin/sup 2/ 2theta>10/sup -4/. It leads to a strong suppression of the neutrino flux even for small sin/sup 2/ 2theta.
