摘要：

We examine the neutrino mass matrix in the version of Zee model where both Higgs doublets couple to the leptons. We show that in this case one can accommodate the large mixing angle (LMA) MSW solution of the solar neutrino problem, while avoiding maximal solar mixing and conflicts with constraints on lepton family number-violating interactions. In the simplified scenario we consider, we have the neutrino mass spectrum characterized by m(1) similar or equal to m(2) similar or equal to root Deltam(atm)(2)/sin 2 theta and m(3)/m(1) similar or equal to cos 2 theta, where theta is the solar mixing angle.
