Supersonic cooling of short-lived molecular states in a pulsed microcavity plasma jet
"Electronic states of helium diners having potential energy > 24 eV and radiative lifetimes as short as 19 ns have been generated in a micro-plasma jet at super-atmospheric pressure and rotationally cooled by supersonic expansion. Spatial-temporal spectrograms of d^3Σ+u→(b^3)π_g (v', v"") = (0, 0) …

Pulsed plasma microjets: a new tool for the investigation of plasma kinetics and molecular spectroscopy
… suitable both for generating and quickly cooling short-lived molecules, and also for studying the kinetics and dynamics that take place at the rotational level during the expansion process. By integrating a microplasma device with a supersonic nozzle, temperatures as low as 50 K were achieved for …
