Summary
In the course of studying a large number of decays of hyperons, produced in our hydrogen bubble chamber by 1.23 BeV/c pions, we have found an unambiguous case of a undergoing beta decay. To our knowledge this is the first leptonic decay seen. (Extracted from the introductory part of the paper.).
