The neutrino decay solution of the solar neutrino problem is revisited in the context of majoron models. It is shown that for a particular range of parameters this scenario reconciles both the Homestake data and the Kamiokande data. The prediction for gallium detectors is also given. It is shown that the sensitivity of Borexino is sufficient to observe the solar ν ̄e signal, which is the crucial prediction of this scenario, and to distinguish it from the alternative ν ̄e signal provided by the hybrid models of neutrino oscillation and magnetic moment transitions.
