The cosmological constant problem arises because the magnitude of vacuum energy density predicted by quantum mechanics is about 120 orders of magnitude larger than the value implied by cosmological observations of accelerating cosmic expansion. Recen

${V}^{\ensuremath{-}}$ and ${V}_{\mathrm{Al}}$ centers in MgO have been shown to possess identical electronic $g$ values at low temperatures and this paper reports on the distinction between the two centers. Although these two centers have almost ide

Previous workers have determined that the ${\mathrm{Ag}}^{0}$ center produced in alkali halides doped with silver and $\ensuremath{\gamma}$ or x irradiated at 77 K is a silver atom in a substitutional cation site. Through the use of electron-nuclear

Because of the difficulty of achieving exact stoichiometry during crystal growth, Bismuth Germanate crystals often contain particulates, bubbles and other inclusions. A more fundamental characteristic is the relatively large diffuse scattering exhibi

Single crystals of CaO doped with deuterium have been grown by the submerged-arc-fusion method and ${V}_{\mathrm{OD}}$ centers were produced by $\ensuremath{\gamma}$ irradiation at 77 K. EPR and electron-nuclear double-resonance measurements yield th

We report electron-nuclear double-resonance (ENDOR) measurements of the magnetic hyperfine and electric quadrupole interactions of the /sup 25/Mg neighbors of the V/sup -/ center in MgO for both the single-axial neighbor and the four equatorial neigh
