Structure of and E2 transition in $^{16}$C in a $^{14}$C+n+n model
Abstract
A three-body model of C+n+n is applied to study the energy spectrum and the hindered 2 transition in C. A realistic two-nucleon potential is used for the valence neutrons. Both spin singlet and triplet components for the neutrons are taken into account. The three-body problem with a Pauli constraint is solved in a stochastic variational method. For the n-C potential chosen to reproduce the properties of C, the low-lying energy spectrum agrees reasonably well with experiment, but the ground state is predicted to be about 1 MeV high. The calculated ; value is about twice the measured value if the polarization charge of the valence neutrons is taken to be the same as that required to fit the C data. The correlated motion of the valence neutrons is displayed through the two-neutron density distribution.
