Absolute differential and integral cross sections for charge transfer of state-selected keV oxygen ion with oxygen(2)
Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory ...
A theoretical study of cyanide on alkali-halide and alkali-metal surfaces using density functional theory
Many interesting physical phenomena have been observed in electron-stimulated desorption studies of the cyanide molecule on alkali halide and alkali metal surfaces. We have performed a theoretical investigation of the ...
Interaction of xenon Rydberg atoms near a metallic surface in an electric field
We investigate the interaction of a xenon Rydberg atom with a metallic surface in an electric field. We also present a Stark map for xenon Rydberg atoms. The xenon Rydberg atom is modeled using a pseudopotential fitted to ...
Trapping and evaporation of strontium-87 and strontium-88 mixtures
This thesis describes trapping and evaporative cooling of ultracold 87Sr and 88Sr mixtures in an optical dipole trap to produce the first Bose-Einstein condensate (BEC) of 88Sr. Furthermore, this work presents thermalization ...
Collisional formation of heavy Rydberg ion-pair states
The formation of heavy Rydberg ion-pair states through electron transfer in collisions between K(np) Rydberg atoms and molecules that attach low-energy electrons is investigated. At low n, collisions with a wide variety ...
Lifetimes of weakly bound heavy-Rydberg ion-pair states formed through Rydberg atom collisions with attaching targets
The formation of K+···Cl- heavy-Rydberg ion-pair states through dissociative electron attachment in K(np)/CCl4 collisions is investigated. The product ion-pair states are detected directly by electric ...
AN ATOMIC OXYGEN TARGET FOR DIFFERENTIAL CROSS SECTION MEASUREMENTS
Atomic oxygen, an abundant upper atmospheric species, is an important target in collisions involving fast ions and neutrals precipitating into the Earth's thermosphere. To facilitate the laboratory study of these collisions ...
Optical manipulation of helium(2(3)S) atoms with a diode laser
A commercial Spectra Diode Laboratories, 1.083 $\mu$m diode laser has been used to efficiently spin polarize an atomic beam of He(2$\sp3$S) metastable atoms by optical pumping on the $\rm 2\sp3S\sb1\rightarrow2\sp3P\sb1$ ...
Absolute differential cross-sections for keV energy ion and atom collisions with oxygen atoms
Oxygen atoms are the most abundant constituent in the Earth's atmosphere between 200km and 600km, and thus are the most probable targets for precipitating ions and atoms at these altitudes. Differential cross sections for ...
