Ozone, predicted to be an important intermediate species in T{sub 2} oxidation, was monitored in situ by UV absorption spectroscopy for 0.01-1.0 mol % T{sub 2} in O{sub 2} (1 atm, 298 K). These are the first measurements of a tritium oxidation reacti

We have performed the first resonant excitation of high n states of positronium using two resonantly excited transitions 1S to 2P and 2P to nL. Magnetic and electric fields in the chamber mixed the high n states so that all 1 sublevels were populated

We report light-emission data from a solid deuterium-tritium sample between 2.4 and 4 K. We have measured the relative intensity as a function of temperature both from a steady-state background and pulsed flashes which we stimulate with a small heate

We have performed the first excitation of high-n states of positronium using resonant, two-photon excitation applied to the n=1 to 2 and 2 to n transitions. Absolute values for the line positions were quantitatively determined for n=14 and 15 and com

The authors report optical saturation of the 13S-23P transition in positronium using ultraviolet light from a frequency-doubled, pulsed dye laser. The increase in ground-state annihilation radiation due to magnetic triplet-singlet mixing in the excit

We demonstrate that molecular ions with mass-to-charge ratios (m/z) ranging from a few hundred to 19 050 can be desorbed from whole bacterial spores using infrared laser desorption and no chemical matrix. We have measured the mass of these ions using

We report a narrow electron-spin-resonance (ESR) signal near the free-electron frequency in solid deuterium containing 2{percent} tritium. We speculate that this narrow ESR line is due to localized electrons in bubbles. {copyright} {ital 1996 The Ame

We report an increase in an emission from solid deuterium tritium at 825 nm, while pumping an electron bubble transition centered at \ensuremath{\sim}350 nm. This experiment implies unbound electrons cause the emission at 825 nm. We find this steady-
