Abstract
We apply a three-body model consisting of two valence neutrons and the core nucleus in order to investigate the ground state properties and electric quadrupole transition of the nucleus. The discretized continuum spectrum within a large box is taken into account by using a single-particle basis obtained from a Woods-Saxon potential. The calculated value from the first state to the ground state shows good agreement with the observed data with the core polarization charge which reproduces the experimental value for . We also show that the present calculation accounts well for the longitudinal momentum distribution of the fragment from the breakup of the nucleus. We point out that the dominant ( configuration in the ground state of plays a crucial role in these agreements.
