摘要
The structure of the neutron-rich carbon nucleus C-16 is described by introducing a new microscopic shell model of no-core type. The model space is composed of the 0s. 0p, 1s0d, and 1p0f shells. The effective interaction is microscopically derived from the CD-Bonn potential and the Coulomb force through a unitary transformation theory. Calculated low-lying energy levels of C-16 agree well with the experimental values. The B(E2: 2(1)(+) -> 0(1)(+)) value is calculated with the bare charges. The anomalously hindered B(E2) value for C-16, measured recently, is well reproduced. (c) 2007 Elsevier B.V. All rights reserved.
