Level Structure Of Ag-99, Ag-101, Ag-103 Observed In The Decay Of Light Cd Isotopes

Abstract The decay of 82 s, 101Cd and 462 s, 103Cd has been studied with the ISOLDE facility. In addition several γ-rays belonging to the 99Cd decay have been observed. Single γ-ray, γ-γ-Δt coincidence and conversion electron spectra have been measured using mass-separated samples. Level schemes for 101Ag and 103Ag have been constructed. From log ƒt values for β+ and EC feeding, the deexcitation pattern of the levels and conversion electron data, spin and parity could be deduced for some of the levels. Additional information from in-beam 102, 104Pd(p, 2nγ)101, 103Ag studies was used to confirm several spin assignments. For 99Cd a tentative decay scheme based on energy-sum relations is presented. Systematical trends in the properties of the neutron deficient odd silver nuclei are discussed. The experimental results are compared with theoretical predictions.
