Abstract: The isotopic composition of a multiatomic isotope-bearing species such as CO2 in an analyte is measured by maintaining the analyte in a condition such that isotope-bearing species are present in an excited state and directing light at wavelengths corresponding to transition energies of isotope-bearing species with different isotopes. The interaction between the analyte and light at the different wavelengths is monitored, as by monitoring the optogalvanic effect caused by the light of the different wavelengths. The light may be supplied by a laser (10) including the isotope-bearing species. A stable isotope such as C or O can be used as a tracer in a chemical or biological test and detected using the composition-determining method.

Abstract: Excimers are formed in a gas (30, 130) by applying a pulsed potential between a first electrode (14, 114) and a counter electrode (26, 126) so that corona discharge occurs, substantially without arcing, when the potential is on. The pulses or on-times of the potential desirably are about 100 microseconds or less. Use of a pulsed potential provides greater efficiency than a constant potential. Where the excimer-forming gas is a pure inert gas, the gas desirably contains less than 10 ppm water vapor.

Abstract: A method and apparatus are provided for generating light such as ultraviolet light from excimer-forming gases. Gases are excited by radio frequency alternating current powered electrodes (200, 210) to form excimers that will decay and emit vacuum ultraviolet light. The halogen concentration is optimized so as to optimize emissions from halogen excimers (Z 2 *) or mixed rare gas/halogen excimers (RGZ*). Emissions from rare gas excimers (RG 2 *) are maximized by maintaining the gas in the discharge region at a relatively low temperature, desirably below 700 °K, so that the average kinetic energy of gas particles is less than the vibrational excitation energy of the excimer and substantially less than the dissociation energy of the excimer. Relatively large electrodes (202, 204) can be used to cool the plasma.
