Neutrino mass spectrum is reanalyzed in supersymmetric models with explicit
trilinear R violation. Models in this category are argued to provide
simultaneous solution to the solar and atmospheric neutrino anomalies. It is
shown specifically that large mixing and hierarchical masses needed for the
vacuum solution of neutrino anomalies arise naturally in these models without
requiring any additional symmetries or hierarchies among the trilinear
couplings.Comment: References added and typos correcte
