摘要: After K capture a vacancy exists in the K-shell. An electron-positron pair can be created, electron captured K-shell, and only positron emitted. To search for this effects decay of Bi/sup 206/ into 3.403-Mev level Pb/sup was examined. By measuring spectrum with lens spectrometer, line found which interpreted as monoenergetic positrons from 1.72Mev transition. (W.D.M.)
