    "abstract": "A three-body model of $^{14}$C+n+n is applied to study the energy spectrum\nand the hindered $E$2 transition in $^{16}$C. A realistic two-nucleon potential\nis used for the valence neutrons. Both spin singlet and triplet components for\nthe neutrons are taken into account. The three-body problem with a Pauli\nconstraint is solved in a stochastic variational method. For the n-$^{14}$C\npotential chosen to reproduce the properties of $^{15}$C, the low-lying energy\nspectrum agrees reasonably well with experiment, but the ground state is\npredicted to be about 1 MeV high. The calculated $B(E2$; $2_1^+ \\to 0^+_1)$\nvalue is about twice the measured value if the polarization charge of the\nvalence neutrons is taken to be the same as that required to fit the $^{15}$C\ndata. The correlated motion of the valence neutrons is displayed through the\ntwo-neutron density distribution.",
