For over 40 years, cadmium (Cd) isotopes have played a key role in the study of the collective behaviour in atomic nuclei. Initially, it was believed that their structures could be described within a collective vibrational model, in which the surface of the nucleus oscillates (vibrates) around a spherical equilibrium shape. Subsequent experimental results inspired new calculations using advanced theoretical models of atomic nuclear structure, which predict that the individual excited states in 110Cd and 112Cd nuclei adopt various ellipsoidal shapes.
Recent experiments conducted at the Heavy Ion Laboratory UW made it possible to discriminate between these two fundamentally different interpretations of the structure of cadmium nuclei by determining the shapes of two key states in the 110Cd nucleus.
A broader discussion of the work was presented in the ‘Important Works‘ section on the portal of the Nuclear Physics Section of the Polish Physical Society.
