Abstract:

β-delayed proton precursors 93Pd and 92Rh were produced by the irradiation of 58Ni with a 40Ca beam, and identified using proton-gamma coincidence measurements in combination with a helium-jet fast tape transport system. The half-lives of 93Pd and 92Rh were determined to be 1.3(2), 3.0(8) s, respectively. The measured energy spectrum of β-delayed protons and the estimated relative branching ratios to the final states in the daughter nuclei were fitted by a statistic model calculation, and then the ground-state spin and parity of 93Pd were assigned as 9/2±.
