The excited states of ¹⁶⁰DY Azodi, Hormoz
The gamma-rays and the conversion electrons emitted following the beta decay of ¹⁶⁰Tb--> ¹⁶⁰Dy have been studied using Ge(Li) and Si(Li) detectors. The measured energies and intensities of these transitions, together with the results of gamma-gamma coincidence measurements, have allowed us to construct the decay scheme of ¹⁶⁰Dy. Four new transitions , namely 97.7, 111.8, 148.5 and 320.5 kev, are placed in the decay scheme on the basis of energy fit and coincidence results. The angular momentum and the parity of the excited states of this nucleus have been deduced as confirmations of previous assignments. The energies and the electromagnetic properties of these states are compared to the predictions of the theory of a rigid asymmetric rotor.
