Abstract
In the decay of J128 the intensity of a weak positron activity was measured to be (3.1±0.7)·10−5 per disintegration. The remeasurement of the totalK capture was found to be 0.059±0.007 in agreement with the results of other authors. From this theK/β +-ratio of the decay to the ground state of Te128 is 1800±400. Theoretical calculations ofK/β + for allowed transitions show that the maximum energy of the positrons is 245±12 keV. In the decay of Rh104 and Lu176m no positrons more than 5·10−6 could be detected.
