Impurity states in solid neon∗†

Dynamics of solid neon monolayers.

The dynamics of two-dimensional solid neon is investigated within the self-consistent phonon theory. Phonon frequencies and lifetimes and the one-phonon dynamic form factor are evaluated as a function of temperature and lattice spacing in the self-consistent harmonic approximation with the cubic anharmonic term added. Two-dimensional solid neon is found to be highly anharmonic. It becomes mecha...

Impurity states in Mott insulators

2014 The effect of a point scattering potential on the properties of a nearly half filled narrow energy-band is studied in the limit of strong intra-atomic Coulomb repulsions. The potential needed to localize a state depends on the spin configuration. A localized hole is found to stabilize a ferromagnetic polarization within a few atomic distances from the impurity. The strength of this couplin...

Impurity Induced States

The infrared spectrum of HOOH+ trapped in solid neon.

When a Ne:H(2)O(2) mixture is codeposited at 4.3 K with a beam of neon atoms that have been excited in a microwave discharge, three new, photosensitive absorptions appear which can be assigned to the three infrared-active vibrational fundamentals of trans-HOOH(+). When the Ne:H(2)O(2) deposition system is pretreated with the vapors of D(2)O, the product absorptions include new peaks which can b...

EXPERIMENTAL INVESTIGATION OF THE POPULATION DENSITIES OF LOWEREXCITED STATES OF NEON

Many studies employing various methods have been carried out into the number densities of excited atoms in electrical discharges with inert gases [1,2,3], but the ranges of the discharge current and gas pressure is very limited in them all. In this work, the population densities of 3S, 3s' of neon have been investigated using the atomic absorption method. Since the discharge current and gas...
