Abstract

Studies of the energy and time-resolved fluorescence of NO D2S+ (v = 0) perturbed by inert gas partners (He, Ne, Ar, Kr and Xe) at various pressures were performed by means of synchrotron radiation. With all rare gases, the collision-induced D (v = 0) -> C (v = 0) cascade was obsd. Depopulation cross sections of D (v = 0) by rare gases were derived which are close to the gas kinetic value. The cross sections for Ne, Ar, Kr and Xe fit C. S. Parmenter et al. (1979) correlation in a satisfactory way. NO (D2S+ (3ps))-rare gas van der Waals well depths are derived from the correlation.

Noble gas

The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive element.

Synchrotron radiation

Synchrotron radiation (also known as magnetobremsstrahlung radiation) is the electromagnetic radiation emitted when relativistic charged particles are subject to an acceleration perpendicular to their velocity (a ⊥ v). It is produced artificially in some types of particle accelerators or naturally by fast electrons moving through magnetic fields. The radiation produced in this way has a characteristic polarization, and the frequencies generated can range over a large portion of the electromagnetic spectrum.

Synchrotron light source

A synchrotron light source is a source of electromagnetic radiation (EM) usually produced by a storage ring, for scientific and technical purposes. First observed in synchrotrons, synchrotron light is now produced by storage rings and other specialized particle accelerators, typically accelerating electrons. Once the high-energy electron beam has been generated, it is directed into auxiliary components such as bending magnets and insertion devices (undulators or wigglers) in storage rings and free electron lasers.
