Three-body model calculations for 16C nucleus

Abstract

We apply a three-body model consisting of two valence neutrons and the core nucleus ${}^{14}$C in order to investigate the ground state properties and the electronic quadrupole transition of the ${}^{16}$C 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 B(E2) value from the first 2${}^{+}$ state to the ground state shows good agreement with the observed data with the core polarization charge which reproduces the experimental B(E2) value for ${}^{15}$C. We also show that the present calculation well accounts for the longitudinal momentum distribution of ${}^{15}$C fragment from the breakup of ${}^{16}$C nucleus. We point out that the dominant ($d_{5/2}{)}^2$ configuration in the ground state of ${}^{16}$C plays a crucial role for these agreement.
