Web15 okt. 2024 · Abstract. We present an analysis of the appearance of the Cooper minimum in singly ionized argon in both the photoionization cross-section (PICS) and high-harmonic generation (HHG) spectrum. We employ two computational approaches based on the same R -matrix technique to provide a coherent description of the atomic structure of the Ar+ … Web23 dec. 2002 · The conditions are chosen such that both plasmas are ionizing.

WebHII regions are volumes of ionized gas (on scales of a few tens to a few hundred light years) present in virtually all gas-rich galaxies. These gas regions consist principally of hydrogen but with ∼10% helium and smaller amounts of oxygen, carbon, nitrogen, sulfur, neon, argon, and other trace elements. Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents (argon has the European food additive code E938). Aerial oxidation, hydrolysis, and other chemical reactions that degrade the products are retarded or prevented entirely. Meer weergeven Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). … Meer weergeven Argon (Greek ἀργόν, neuter singular form of ἀργός meaning "lazy" or "inactive") is named in reference to its chemical inactivity. This chemical property of this first noble gas to be discovered impressed the namers.

Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most … Meer weergeven Argon constitutes 0.934% by volume and 1.288% by mass of Earth's atmosphere. Air is the primary industrial source of purified argon products. Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also … Meer weergeven Argon's complete octet of electrons indicates full s and p subshells. This full valence shell makes argon very stable and extremely resistant to bonding with other elements. Before 1962, argon and the other noble gases were considered to be chemically … Meer weergeven
