Electron-induced processes in water ice and CO2 ice are important in planetary science. We have measured desorption yields of positive ion products (C+, O+, D+, D3O+, CO+, O2+) produced as a result of exposing pure CO2 and D2O adsorbed on CO2 ices to

We report studies on the thermal and radiolytic stability of the hydrated salt minerals epsomite (MgSO4·7H2O), mirabilite (Na2SO4·10H2O), and natron (Na2CO3·10H2O) under the low-temperature and ultrahigh vacuum conditions characteristic of the sur

We have studied the electron-stimulated desorption (ESD) of neutral atomic iodine from single crystals of KI(100) using time-of-flight laser-resonance-enhanced multiphoton ionization spectroscopy and quadrupole mass spectrometry. The measured iodine

Low-energy electron-stimulated desorption (ESD) of D + from D 2 O has been used to examine the phase and growth behavior of nanoscale vapor-deposited ice films grown on Pt(111) between 90–155 K. The D + yield from porous amorphous solid water (depo

We describe a new experimental technique utilizing incident beam diffraction in electron stimulated desorption (ESD) to determine the initial atomic bonding structure of desorbates. Diffraction in ESD can provide detailed information about the ground

The total electron-stimulated desorption yield of Cl{sup +} ions from the Cl-terminated Si(111) surface is shown to exhibit fine-structure oscillations as a function of incident electron beam direction. We demonstrate that this fine structure is cons

The electron-stimulated desorption (ESD) of D− ions from condensed D2O films is investigated. Three low-energy peaks are observed which are identified as arising from excitation of 2B1, 2A1, and 2B2 dissociative electron attachment (DEA) resonances

The electron-stimulated desorption (ESD) of D+ from microporous D2O ice films condensed on Pt(111) has been investigated. The total D+ yield as a function of temperature from 90–180 K depends sensitively on the film roughness, surface temperature a

Branching-ratio photoelectron holography has been employed to study the structure of Sb adsorbed on Si(111). The Sb 4d corelevel emission was measured as a function of emission direction, and the branching ratio between the two spin-orbit-split compo
