Gamma-gamma Directional Correlations in¹⁰³Rh

Abstract

Gamma-gamma directional correlations in 103Rh were measured in the decay of 103Ru. No dependence on the chemical composition of the source was observed. The following directional correlation coefficients were determined: A2(557 - 53) = -0.064 ± 0.003, A2(444 - 53) = -0.035 ± 0.013. The lifetime of the 93 keV state was measured as T½ = 1.06 ± 0.05 ns. By use of this value for the lifetime and the rotation in an external magnetic field of the directional correlation pattern, the gyromagnetic factor of the 93 keV state is obtained as g = 1.07 ± 0.17. The properties of 103Rh were calculated on basis of the unified vibrational model. The adequacy of this model for describing the positive-parity states studied in this work is discussed.
