Abstract

The triton energy spectrum of the muon capture reaction µ3He→t+νµ where µ3He is the ground state of muonic3He, has been measured by means of a high-pressure ionization chamber in order to investigate a possible heavyv admixture into the µ flavor with high sensitivity. The upper limit of the µ-heavy vi mixing matrix element squared was obtained to be ∣Uµi2⩽10−3 for heavy neutrino masses in the range of 25⩽ E0V⩽75 MeV.
