摘要：

The three-body model of C-14+n+n is applied to study the E2 transition in C-16. The n-C-14 potential is chosen to reproduce the single-particle energies of C-15. The wave functions of C-16 are obtained as a combination of correlated Gaussians by including the Pauli requirement. It is found that the hindered E2 transition can be accounted for by a polarization charge of about 0.10e while the E2 transition in C-15 requires a little larger charge of 0.16e. The soundness of this result is contrasted to the E2 transitions in (O-17, O-18) and (F-17, Ne-18) nuclei. The longitudinal momentum distribution of C-15 fragments from C-16 breakup can be well reproduced.
