Description

Classical macroscopic considerations indicate that the nuclear surface energy is too strong to allow shape vibrations of the nucleus low enough in energy to be found within the pairing gap. The experimental evidence for the need for configuration dependent pairing to explain low-lying ex-“β vibration” 0+ states in deformed nuclei will be reiterated. The low-lying Kπ=2+ ex-“γ vibration” states observed in most deformed nuclei are evidence for the breaking of axial symmetry. The success of recent very sophisticated relativistic mean field and triaxial projected shell model calculations will be discussed.
