Comment on "Shape and superdeformed structure in Hg isotopes in relativistic mean field model" and "Structure of neutron-deficient Pt, Hg, and Pb isotopes"

Abstract

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. [Phys. Rev. C 50, 1924 (1994)] and S. Yoshida et al. [Phys. Rev. C 50, 1398 (1994)] contradict the large body of experimental data on these nuclei. In particular, we question their predictions of deformed ground states in the Pb isotopes and prolate and superdeformed ground states in the Hg isotopes. \textcopyright{} 1996 The American Physical Society.
