The energy spectra of fast (10¹−10² keV) electrons accompanying π⁺ → μ⁺ decays of positively charged pions (π⁺) stopped in a nuclear emulsion are obtained. These spectra are compared with the analogous spectra obtained earlier for electrons accompanying the decay μ⁺ → е⁺. The comparison in question confirms qualitatively the hypothesis that, in either process, fast electrons appear via the mechanism based on Migdal’s shakeup effect.
