Relativistic mean field model for isotopic shifts of odd-A Bi isotopes

The results of relativistic mean field (RMF) calculations for the ground-state properties of odd-A Bi isotopes are presented using the most successful nonlinear sets of Lagrangian parameters. The calculated quadrupole moments are found to increase as neutrons are added or removed from the N = 126 shell. However, no corresponding increase is revealed in the calculated charge radii. This observation is consistent with recent experimental findings. [S0556-2813(99)02206-2]
