The quadrupole ion mass spectrometer (QIMS) measured fluxes of barium and strontium ions during the CRRES G-1 chemical release in full Sun and the G-11b release in darkness. The barium ion fluxes detected in darkness were only a factor of 10 lower th

Mass resolved fluxes of Ba{sup +} and Sr{sup +} ions were measured with the Quadrupole Ion Mass Spectrometer during the CRRES G-11b chemical release experiment in darkness. The flux of Sr{sup +} relative to Ba{sup +} at a distance of 4 km from the re

We describe the very-early-time expansion processes (≈0 - 3 s) of the CRRES G-9 Ba+/Li+ cloud release, as manifested by thermal- and photo-ionization mechanisms, by coupling to the background ionosphere, and by differential acceleration of multi-io

A straightforward approach to calculating number densities of barium ions at the satellite position following CRRES low altitude chemical releases is described. The calculation is based on a phenomenological model of the neutral barium cloud which is

The vibrational distribution of the O2+ product ion in the reaction of O+ with CO2 has been measured in a selected ion flow tube using the monitor ion technique. At 300 K the measured vibrational distribution is 45% of the ions in υ = 1, 32% in υ
