Abstract

Multiconfiguration Dirac-Fock models have been employed to compute the electric field gradient in the ground state of the neutral bismuth atom. Combined with the experimental electric quadrupole hyperfine interaction constant, one obtains for 209Bi the nuclear quadrupole moment Q=516(15)mb, which is almost 40% away from the previously accepted standard value [ 370(26)mb], and narrows by over an order of magnitude the long-standing, extremely broad array of various results ranging from 370 to 710mb. The recent Q values of 202208,210m213Bi by Pearson et al. suffer a consequent change.
