Decay of 40 d 103Ru and 17 d 103Pd to levels of 103Rh

The structure and properties of the levels of ¹⁰³Rh have been further characterized by studying the electrons and γ-rays emitted in the decay of 40 d ¹⁰³Ru and 17 d ¹⁰³Pd. K-conversion coefficients of 0.0043±0.0006 and 0.0025±0.0005 have been measured for the 497 and 610 keV γ-transitions respectively and indicate positive parity for the 537 and 650 keV levels. Using a time-to-amplitude conversion system, an upper limit of 0.4 ns has been determined for the lifetime of the 93 keV level. Angular correlations have been observed for the 444-53 and 557-53 keV cascades and indicate spins of {5}/{2} or {7}/{2} for the levels at 537 and 650 keV. A weak 242 keV γ- ray from the 537 keV level to the {3}/{2}^- level at 295 keV establishes the spin and parity of the 537 keV level as {5}/{2}⁺. The log ft values for the β^- decay and E. C. decay to the levels of ¹⁰³Pd have been determined and sizeable hindrances noted.
