Abstract
The intensity of broad quartet signal often identified as methyl radic al(. CH3) in alkali feldspars is enhanced by gamma-irradiation. The av erage g factor and hyperfine A of the broad distorted quartet signal a re g = 2.0033 and A = 2.45 mT, respectively, and were previously ident ified as . CH3 or . C2H5. The intensity of the quartet signal is enhan ced by two orders of the magnitude by hydrothermal experiments of Na-f eldspars in NH3 atmosphere and therefore the signal was identified as . NH3+ where the anisotropic hyperfine due to N (I = 1) is not observe d due to broadening in the powdered spectrum. Copyright (C) 1996 Elsev ier Science Ltd
