Abstract

We describe the details of an experiment designed to search for the admixture of massive neutrinos into electron-flavor neutrinos by observation with high resolution of the positron momentum spectrum in $π \to e + ν$ decay. No indication was found for such an admixture and the corresponding mixing amplitude was constrained below the $U_{ei}^{2} \leq 10^{- 6}$ region for neutrinos of ∼30 MeV/ $c^{2}$ mass.
