A Study of the Residual 39Ar Content in Argon from Underground Sources [PDF]
Astroparticle Physics, Volume 66 (2015) 53-60, 2012 The discovery of argon from underground sources with significantly less 39Ar than atmospheric argon was an important step in the development of direct-detection dark matter experiments using argon as the active target.

Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors [PDF]
J.Phys.Conf.Ser.120:042015,2008, 2007 We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39Ar.

A Study of Dielectric Breakdown Along Insulators Surrounding Conductors in Liquid Argon [PDF]
, 2016 High voltage breakdown in liquid argon is an important concern in the design of liquid argon time projection chambers, which are often used as neutrino and dark matter detectors.

Discovery of photospheric argon in very hot central stars of planetary nebulae and white dwarfs [PDF]
, 2007 We report the first discovery of argon in hot evolved stars and white dwarfs. We have identified the ArVII 1063.55A line in some of the hottest known (Teff=95000-110000 K) central stars of planetary nebulae and (pre-) white dwarfs of various spectral ...

Nature, 1904 IN your translation of Prof. Mendeleeff's interesting paper on the chemical elements (November 17, p. 94) I see that he attributes the discovery of argon and its congeners to Ramsay. Am I not right in believing that it was Lord Rayleigh who discovered argon, and that it was he who gave that impulse to chemistry which Sir William Ramsay has carried ...

Direct dating of overprinting fluid systems in the Martabe epithermal gold deposit using highly retentive alunite [PDF]
Geochronology, 2023 The Martabe gold deposits in Sumatra formed in a shallow crustal epithermal environment associated with intermediate mafic intrusions adjacent to an active right-lateral wrench system. Gas/fluid temperatures reached 200–350 ∘C.

Analysis of argon isotope separation by low temperature adsorption [PDF]
MATEC Web of Conferences, 2020 In this work, the estimated calculated values of the critical parameters of argon isotopes 36Ar, 38Ar, 40Ar and the corresponding values of the constants of the Van der Waals, Redlich-Kwong and Peng-Robinson equations of state are obtained.
