The Decay Scheme ofAg108

Abstract

The radiations of 2.3-minute ${\mathrm{Ag}}^{108}$ have been examined with scintillation and proportional counter spectrometers and with a coincidence spectrometer. The transitions and their abundances were found to be as follows: ${\beta }^{-}$ 1.77 Mev (97.3 percent); ${\beta }^{-}$ 1.15 Mev accompanied by $\gamma$ of energy 0.62 Mev (0.8 percent); ${\beta }^{+}$ (0.14 percent); and $K$ capture to ground and excited states of ${\mathrm{Pd}}^{108}$ (1.6 percent). Gamma rays of energies 0.60 Mev and 0.43 Mev were found to accompany $K$ capture; the abundances of the different capture transitions were measured. Spin and parity assignments were made.
