Radioactive decay of 4.4-hRu105to levels ofRh105

The energies, intensities and coincidences of the $\gamma$ rays following the radioactive decay of 4.4-h ${}_{}{}^{105}{}_{}{}^{}\mathrm{Ru}$ to levels of ${}_{}{}^{105}{}_{}{}^{}\mathrm{Rh}$ have been determined. 85 $\gamma$ rays have been fit into a level scheme between 25 excited states. Spin and parity assignments are deduced and discussed as are the results of earlier ${}_{}{}^{104}{}_{}{}^{}\mathrm{Ru}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{105}{}_{}{}^{}\mathrm{Rh}$ and ${}_{}{}^{108}{}_{}{}^{}\mathrm{Pd}(p, \alpha ){}_{}{}^{105}{}_{}{}^{}\mathrm{Rh}$ reaction studies. The level structure of ${}_{}{}^{105}{}_{}{}^{}\mathrm{Rh}$ is compared with other odd-mass $41\le Z\le 49$ nuclides and the presence of strong $E1-\frac{M1\mathrm{}}{E2\mathrm{}}$ competition discussed.
