Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule

The x‐ray type factors for a guaranteed H within the H molecule are calculated for a spherical approximation to the guaranteed atom. These factors could also be higher suited to the least‐squares refinement of x‐ray optical phenomenon information from organic molecular crystals than those for the isolated atom. it’s been shown that at intervals the spherical approximation for the guaranteed hydrogens in H2, a least‐squares refinement of the atomic positions can lead to a bond length (Re value) wanting nucleon optical phenomenon or chemical analysis values. The spherical atoms area unit optimally positioned zero.07 Å off every nucleon into the bond. A round shape density for the guaranteed atom within the H molecule has additionally been outlined and therefore the corresponding advanced scattering factors are calculated. [1]

Hydrogen atom in a strong magnetic field

The energy levels and wave functions ar studied for a atom during a} very robust field of force. The contraction of the electronic-charge distribution in an exceedingly plane perpendicular to the field of force leads to a rise in ionization energy at high fields. Conditions ar favorable for perceptive the result within the case of impurity states in an exceedingly semiconductor of high stuff constant and low effective mass, to that the speculation is applied very well. Changes within the optical and electrical properties ar foreseen. [2]

The partial wave theory of electron-hydrogen atom collisions

The paper is bothered with the answer of the algebraical issues arising within the partial wave treatment of electron-hydrogen atom collisions. expressly antisymmetrized wave functions ar used throughout. The boundary conditions ar written in S-matrix notation and expressions for total and differential cross-sections obtained. The algebraical coefficients fλ and gλ occurring within the continuous state Hartree-Fock equations ar expressed in terms of Racah coefficients, and tabulated as functions of the whole momentum for atomic s, p and d leptons and every one angular momenta of the scattered electron. Expressions ar given for the calculation of first-order corrections to the results obtained mistreatment approximate wave functions. [3]

Interstitial hydrogen atoms in face-centered cubic iron in the Earth’s core

Hydrogen is probably going one in every of the sunshine components within the Earth’s core. Despite its importance, no direct observation has been manufactured from H in Associate in Nursing iron lattice at high. we have a tendency to created the primary direct determination of web site occupancy and volume of opening H in a very face-centered solid (fcc) iron lattice up to 12 GPa and 1200 K mistreatment the in place nucleon optical phenomenon methodology. The transition temperatures from the body-centered solid and also the double-hexagonal compact sections to the FCC phase were more than rumored antecedently. At pressures  0.8 with increasing pressure. [4]

Superluminal Hydrogen Atom in a Constant Magnetic Field in (3+1)-dimensional Spacetime (II)

As has typically been the case within the tradition of some scientific novel ideas, we have a tendency to use the atom as a “test particle”, within the context of superluminal phase space theory. In Paper (I) of this series, the elemental impact of AN applied external force field on a transversally guided  beam of hydrogen-like atoms is uncovered, that of transformation from spherical wave enlargement into plane wave perform. This ends up in AN unprecedented  idea of a tabular coiled element field, with a time of linear momentum in (3+1)-dimensional spacetime. Thereupon, we have a tendency to investigate a doable “superluminality” of this field. [5]
