Superdeformation and α-cluster structure of the nucleus 36Ar Original Research Article

The structure of the nucleus 36Ar is investigated by the View the MathML source orthogonality condition model (OCM). The energy spectra, electromagnetic transitions and α spectroscopic factors for the View the MathML source channels are calculated and discussed. It is shown that the observed energies and E2 transitions of the superdeformed (SD) band are well reproduced by the cluster model. It is discussed that the SD band is constructed as a result of band crossing of View the MathML source cluster bands. The existence of a negative-parity doublet band of the SD band is predicted. The strength of the α-cluster states is shown to be spread over several levels due to mixing of shell-model states and various α-cluster states.
