Cluster structure and collective behavior of the nucleus 48Cr Original Research Article

The structure of the nucleus 48Cr was investigated by the View the MathML source orthogonality condition model (OCM). The energy spectra, electromagnetic transitions, and spectroscopic factors for the View the MathML source and View the MathML source channels were calculated and are discussed herein. The observed energies and E2 transitions of the yrast band, which show collective behavior, were found to be well reproduced by the cluster model. Some exotic 2α-cluster states with “Ca–α–α”- and “α–Ca–α”-like configurations are predicted near the 2α threshold. The structures of the states were analyzed through the wave functions. The mechanism of backbending of the yrast band can be explained naturally in terms of the cluster-coupling scheme.
