Department of Physics, Florida State University, 32306, Tallahassee, FL, USA aut A new cluster model interpretation of the anomalous lifetime of 14C [Elektronische Daten] [D. Robson] A new cluster model solution to the long-standing nuclear structure problem of describing the anomalously long lifetime of 14C is presented. Related beta-decay data for 14O to states in 14N, gamma-decay data between low-lying positive parity states in 14N and the elastic and inelastic magnetic dipole electron scattering from 14N data are all shown to be very accurately described by the model. The shapes of the beta spectra for the A = 14 system are also well reproduced by the model. The model invokes four-nucleon tetrahedral symmetric spatial correlations arising from three- and four-nucleon interactions, which yields a high degree of SU(4) singlet structure for the clusters and a tetrahedral intrinsic shape for the doubly magic 16O ground state. The large quadrupole moment of the 14N ground state is obtained here for the first time and arises because of the almost 100% d-wave deuteron-like-hole cluster structure inherent in the model.
