Decays of 108m+gIn and 106m+gIn

The isotopes 108 Cd and 106 Cd have been studied from the β + /EC decay of 108m + g In and 106m + g In with the ISOCELE facility. Gamma-ray, conversion electron, γγt and e − γt coincidence measurements have been performed and level schemes of 108 Cd and 106 Cd have been built. A 0 + excited state has been clearly established at 1913.2 keV in 108 Cd. The properties of the excited states are discussed in terms of the vibrator-plus-particle approach and the interacting boson approximation. The present results lead us to assign the spin and parity value I π = 7 + for the isomeric state in 108 In and in 106 In; this is discussed in the framework of the jj -coupling model.
