Electron Recombination with Small Molecular Ions
In this thesis I have theoretically studied electron recombination processes with small molecular ions. In these kind of processes resonant states are involved. To calculate the potential energy for these states as a function of internuclear distance, structure calculations and scattering calculations have to be performed. So far I have been studying the ion-pair formation with in electron reco...
متن کاملColour centres in LiF : Mg crystals
— Two types of H° centres and one H~ centre were found by ESR and vacuum UV measurements in X-irradiated LiF : Mg. The so called Z3 and Z2 centres in LiF : Mg are not identical with any Z centre and are rather connected to the OH impurity.

متن کاملVisualization of the impurity depletion zone surrounding apoferritin crystals growing in gel with holoferritin dimer impurity
Colorless apoferritin (MD450 kDa) crystals were grown in the presence of red colored holoferritin dimers (MD900 kDa) within agarose gel by counterdiffusion with Cd as precipitant. In agreement with our previous quantitative measurements showing preferential trapping of dimers (segregation coefficient K 1⁄4 4), the apoferritin crystals became darkly colored while the gel solution around them was...
متن کاملDimension changes due to aligned V , centres and H centres in ionic crystals
When anisotropic defects are aligned, the dimensions of the host crystal parallel and perpendicular to the defect axis are changed, an effect observed previously for €3 centres and V, centres in KC1. We have calculated the effect for H centres and V, centres in several crystal structures. The contribution from long-range Coulomb interactions has been obtained in all cases, with less-detailed es...
