Decays ofRh106andAg106

The gamma-ray spectra of 30-sec ${\mathrm{Rh}}^{106}$ and 8.3-day ${\mathrm{Ag}}^{106}$, which both decay to ${\mathrm{Pd}}^{106}$, have been studied with scintillation spectrometers. Three gamma-gamma angular correlations have also been measured. The results are consistent with the following level scheme for ${\mathrm{Pd}}^{106}$: 0.513(2+), 1.131(2+), 1.137(0+), 1.360 or 1.213, 1.563(2+), 1.73(2 or 3), 1.84, 1.88, 1.94(3- or 4+), 2.01, 2.052(4+), 2.09(3), 2.28, 2.305 (3 or 4), 2.352(4+), 2.46, 2.62, 2.764(5-), 2.87, and 3.08 Mev. The transition between the first and second 2+ levels was found to consist primarily of $E2\mathrm{}$ radiation. The branching ratio obtained for the cascade to crossover gamma rays from the second 2+ level is 2.1±0.3. This ratio combined with Coulomb excitation data of Stelson and McGowan gives a value of 1.0±0.3 for the ratio $\frac{B(E2, 2^{\prime }\to 2)}{B(E2, 2\to 0)}$.
