  The experimental test of possible expansion for the Higgs sector is proposed.
The lepton family violation will be studied. To reach this goal we are going to
carry out the search for the scalar Goldstone boson in the neutrinoless muon
decay mu+ to e+ and alpha. The asymmetry of the muon decay near the high energy
edge of Michel spectrum is to be measured. To examine previous TRIUMF data the
experiment FAMILON is prepared at the surface muon beam of JINR (Dubna)
accelerator. The setup consist of the precision magnetic spectrometer and the
device for muSR - analysis.
