SHAPE AND SUPERDEFORMED STRUCTURE IN HG ISOTOPES IN RELATIVISTIC MEAN-FIELD MODEL AND STRUCTURE OF NEUTRON-DEFICIENT PT, HG, AND PB ISOTOPES - COMMENT

We point out that the results of relativistic mean field calculations for neutron-deficient Pt, Hg, and Pb isotopes by S. K. Patra et al. [P hys. Rev. C 50, 1924 (1994)] and S. Yoshida et al. [Phys. Rev. C 50, 1 398 (1994)] contradict the large body of experimental data on these nu clei. In particular, we question their predictions of deformed ground states in the Pb isotopes and prolate and superdeformed ground states in the Hg isotopes.
