Vibrational spectra of defects in silicon: An orbital radii approach.
A phenomenological approach to the stretching mode vibrational frequencies of defects in semiconductors is proposed. A novel quantum scale is defined in terms of the first principles pseudopotential based orbital radius rs and the principal quantum number of the element concerned. A universal linear relationship between the Sanderson electronegativity (SR ) and this quantum scale is established...
متن کاملMigration of extrasolar planets to large orbital radii
Observations of structure in circumstellar debris discs provide circumstantial evidence for the presence of massive planets at large (several tens of AU) orbital radii, where the timescale for planet formation via core accretion is prohibitively long. Here, we investigate whether a population of distant planets can be produced via outward migration subsequent to formation in the inner disc. Two...
متن کاملAtomic radii of noble gas elements in condensed phases
Neutral atomic radii of dissolved noble gas elements in condensed phases are obtained by treating the neutral atoms as "ions" of zero oxidation state and by interpolation from a plot of radius vs. oxidation state for isoelectronic ions. The major assumption is that the radius of an ion or a neutral atom having an electronic configuration of a noble gas element depends primarily on the interacti...
متن کاملCorrigendum: Atomic and Ionic Radii of Elements 1-96.
Atomic and cationic radii have been calculated for the first 96 elements, together with selected anionic radii. The metric adopted is the average distance from the nucleus where the electron density falls to 0.001 electrons per bohr(3) , following earlier work by Boyd. Our radii are derived using relativistic all-electron density functional theory calculations, close to the basis set limit. The...
متن کاملAtomic parity nonconservation and neutron radii in cesium isotopes.
The interpretation of future precise experiments on atomic parity violation in terms of parameters of the Standard Model could be hampered by uncertainties in the atomic and nuclear structure. While the former can be overcome by measurement in a series of isotopes, the nuclear structure requires knowledge of the neutron density. We use the nuclear Hartree–Fock method, which includes deformation...
