Radioactive decay of Re188

The spectra of negatons, conversion electrons and photoelectrons were measured with the iron-yoke double focusing spectrometer. Two-groups with end-point energies 2128 and 1973 keV andlgf values 8.04 and 8.41 respectively were observed. TheK andL conversion coefficients of 155.0 keV transition were found to be in agreement with theoretical prediction within a few per cent. Three new-transitions, 635, 1175 and 1461 keV, were observed and some corrections of the decay scheme were made. The possible interpretations of the excited states are discussed.
