Radiolysis of Aqueous Methane Solutions

Authors: G.C. Stevens, R.M. Clarke, E.J. Hart The gamma-ray and electron pulse irradiation of aqueous methane and some ethane solutions is reported. The ab- sorption spectra of the CH3 and C2H5 free radicals have been measured in the wavelength range 210-270 nm. At 210 nm e(CH3) = 850 M-1 cm-1 and e(C2Hs) = 520 M-1 cm-1. The bimolecular recombination rate…

Spectroscopic investigations of high-energy-density plasma transformations in a simulated early reducing atmosphere containing methane,

Authors: M. Civiš, M. Ferus, A. Knížek, P. Kubelik, M. Kamas, P. Španel, K. Drahina, V. Shestivska, L. Juha, P. Skrehot, V. Laitl, S. Civiš Large-scale plasma was created in gas mixtures containing methane using high-power laser-induced dielectric breakdown (LIDB). The composition of the mixtures corresponded to a cometary and/or meteoritic impact into the early atmosphere of either Titan or…
