Abstract

The paper describes the measurement of the angular distribution of electrons at the decay ofΜ-mesons in a longitudinal magnetic field. The results of measurement indicate that electrons are emitted with preference not only in the direction parallel to the spin orientation of Μ-meson but also in the antiparallel direction in disagreement with the angular distribution predicted by theory.
