Gas-Phase Reactions of Negative Ions at Hyperthermal Energies
Abstract
A tandem mass spectrometer incorporating radio-frequency octupole ion guides has been designed, constructed, and tested. This instrument is capable of measuring absolute integral cross sections for gas-phase ion molecule reactions as functions of the reactants relative translation energy from thermal to hyperthermal energy (0.03 - 20 eV c.m.), and of the neutral reactant's temperature from 298 - 1000 K. A series of calibration studies have been carried out to verify the operating characteristics of this new instrument.
