Abstract
The electric quadrupole moment for the state of , has been calculated using the relativistic coupled-cluster method. Earlier a similar calculation was performed for the state of which is the most accurate determination to date [Sur et al., Phys. Rev. Lett. 96, 193001 (2006)]. The present calculation of the electric quadrupole moment of yielded a value where the experimental value is ; is the Bohr radius and the elementary charge. We discuss in this paper our results for in detail and highlight the dominant correlation effects present. We have presented the effect of inner core excitations and their contribution to the electric quadrupole moment, which is a property sensitive to regions away from the nucleus.
