Query: Nonadiabatic Atomic-like State Stabilizing Antiferromagnetism and Mott
  Insulation in MnO   In this paper I report evidence that the antiferromagnetic and insulating
ground state of MnO is caused by a nonadiabatic atomic-like motion as it is
evidently the case in NiO. In addition, I show that the experimental findings
of Goodwin et al. [Phys. Rev. Lett. (2006), 96,~047209] corroborate my
suggestion that the rhombohedral-like distortion in antiferromagnetic MnO as
well as in antiferromagnetic NiO is an inner distortion of the monoclinic
base-centered Bravais lattice of the antiferromagnetic phases.
