Determination of the characteristics of crystalline rocks by field experiments: a review
Autor: J. D. Mather, F. P. Sargent
Publikováno v: Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences. 319:139-156
Crystalline rocks, particularly granitic rocks and basalts, are one of the principal rock types under consideration as a potential host rock for a high-level radioactive waste repository. Permeability in such rocks is related to discontinuities of va

Radiation chemistry of low-temperature aqueous glasses. Part 4.—Distinguishable electron traps in neutral and alkaline glasses
Autor: F. P. Sargent, T. E. Lantz, G. V. Buxton, F. S. Dainton
Publikováno v: Trans. Faraday Soc.. 66:2962-2973
Extensive studies of the photobleaching kinetics of e–t in aqueous alkaline glasses show (i) that electrons are trapped in potential wells of differing depths from which they can be selectively photo-bleached, and (ii) that trapping occurs within t

Spin trapping of radicals produced in benzene radiolysis. Evidence for the phenyl radical as an intermediate
Autor: E. M. Gardy, F. P. Sargent
Publikováno v: The Journal of Chemical Physics. 67:1793-1795
The spin trapping technique has been used to show that phenyl radicals are produced during the radiolysis of benzene. (AIP)

Electron spin resonance studies of radiation damage. Part I. An alternating linewidth effect for the (CH3)2ĊOH radical in gamma-irradiated acetone at low temperatures
Autor: F. P. Sargent
Publikováno v: Canadian Journal of Chemistry. 46:1029-1031
The e.s.r. spectrum of the (CH3)2ĊOH radical showed a drastic temperature dependence of linewidth in the range −196 to −100 °C, this being particularly pronounced for the M1 = ±2 lines. Possible mechanisms are discussed in terms of restricted

Electron Spin Resonance Studies of Radiation Damage. Part. V. γ-Radiolysis and Photolysis of Aqueous Alkaline Glasses Containing Acetonitrile. The Photo Conversion of an Imino Radical to an Alkyl Radical at 77 °K
Autor: F. P. Sargent, M. G. Bailey
Publikováno v: Canadian Journal of Chemistry. 49:3898-3900
The reactions of γ and photochemically produced electrons with acetonitrile in 8 M sodium hydroxide glasses at 77 °K have been re-investigated. The results differed from those previously reported and a novel photo-conversion of an imino radical to

The Electron Spin Resonance Spectra of the Photochemically Produced Perfluorobenzophenone Ketyl and Anion Radicals
Autor: M. G. Bailey, F. P. Sargent
Publikováno v: Canadian Journal of Chemistry. 49:2350-2352
The electron spin resonance spectra of the ketyl and radical anion of perfluorobenzophenone were generated in alcoholic solution by means of a photochemical method. The radical anion was prepared in alkaline solutions by means of a flow system to pre

Electron spin resonance studies of radiation damage. Part IV. The effect of photobleaching on the trapped radicals in gamma irradiated 2-methyltetrahydrofuran glasses at 77 °K
Autor: F. P. Sargent
Publikováno v: Canadian Journal of Chemistry. 48:3453-3455
The concentration of trapped radicals was found to decrease during the course of photobleaching trapped electrons in gamma irradiated 2-methyltetrahydrofuran glasses at 77 °K.
