Diffusion model for relativistic heavy-ion collisions

The decay of 2.4 h^117g Cd and 3.4 h^117m Cd has been investigated with the use of high-resolution Si(Li) and Ge(Li) detectors, also in an anti-Compton arrangement. Spectra from the two isomers have been resolved by comparing young reactor-produced¹¹⁷Cd with aged cyclotron-produced¹¹⁷Cd. Ge(Li)-Ge(Li) coincidences have been measured with a multi-parameter analyzer. A hundred observedγ-rays are placed in a level scheme of¹¹⁷In. Possible theoretical interpretations are discussed. The I.T. Branching of¹¹⁷In is (47.1±1.5)%. Only about 1% of 11/2^{? 117m} Cd decays to 1.93 h 1/2^{? 117m} In and 10.9% of 1/2^{+ 117g} Cd decays to the 9/2^{+ 117g} In ground state bypassing the isomeric In state.
