	C&EN: SCIENCE & TECHNOLOGY - INTERSTELLAR CHEMISTRY
		In their ultra-high-vacuum experiment, a beam of hydrogen atoms, cooled to 150 to 200 K, was directed at a very cold (5 to 15 K) olivine surface, a silicate mineral chosen for its resemblance to silicate interstellar dust particles.
		In a recent series of experiments, Fraser and her Leiden colleagues have reexamined the formation of carbon dioxide in ices in the presence of an energy source such as ultraviolet light.
		Experiments conducted at Leiden and elsewhere beginning in the 1970s showed that carbon dioxide can form when an ice containing carbon monoxide is irradiated with UV light in the presence of oxygen atoms.

		In the scientific method, an experiment is a set of actions and observations, performed to verify or falsify a hypothesis or research a causal relationship between phenomena.
		The word "experience" may refer (somewhat ambiguously) both to mentally unprocessed immediately-perceived events as well as to the purported wisdom gained in subsequent reflection on those events or interpretation of them.
		First-hand experience of the "you had to be there" variety can seem especially valuable and privileged, but it often remains potentially subject to errors in sense-perception and in personal interpretation.

	Interstellar cloud - Wikipedia, the free encyclopedia
		The fact that they were found indicates that these chemical reactions in interstellar clouds take place faster than suspected.
		These reactions are studied in the CRESU experiment.
		These interstellar clouds possess a velocity higher than can be explained by the rotation of the Milky Way.

		The CRESU apparatus and the PLP-LIF technique have been extensively described elsewhere (Sims et al.
		This is very specific as, usually, state-to-state studies are not possible using the CRESU apparatus since collisional relaxation time scales are much shorter than the reaction time scale.

	Experimental section
		The fundamentals of the CRESU technique have been described in detail previously [Sims et al.
		Only the essential features of the experiment, therefore, will be reported here.
		Low temperatures were achieved via the isentropic expansion of a buffer gas (argon in this study) through a suitably designed Laval nozzle.
