Journal ArticleDOI
Anomalous μ + Precession in Silicon
Jess H. Brewer,Kenneth M. Crowe,F.N. Gygax,R.F. Johnson,B.D. Patterson,Donald G. Fleming,A. Schenck +6 more
TL;DR: In this article, the authors studied the precession of polarized positive muons in quartz and silicon in transverse magnetic fields, via the asymmetric decay, and observed free muon precession and two-frequency muonium precession, as well as two anomalous precession frequencies apparent only in silicon.
Journal ArticleDOI
Kinetic Isotope Effects for the Reactions of Muonic Helium and Muonium with H2
Donald G. Fleming,Donald J. Arseneau,Oleksandr Sukhorukov,Oleksandr Sukhorukov,Jess H. Brewer,Steven L. Mielke,George C. Schatz,Bruce C. Garrett,Kirk A. Peterson,Donald G. Truhlar +9 more
TL;DR: Calculated reaction rates for two hydrogen isotopes, one 36 times heavier than the other, agree with experiments at 500 kelvin, and variational transition-state theory is used to interpret the extremely low kinetic isotope effects in the 10−4 to 10−2 range.
Journal ArticleDOI
Experimental tests of reaction rate theory: Mu+H2 and Mu+D2
TL;DR: In this paper, the authors reported the Bimolecular rate constants for the thermal chemical reactions of muonium (Mu) with hydrogen and deuterium (Deuterium) over the temperature range 473-843 K.
Journal ArticleDOI
Production of thermal muonium in the vacuum between the grains of fine silica powders
TL;DR: When spin-polarized positive muons are stopped in fine SiO 2 powder under vacuum, muonium precession was observed indicating 45% formation as discussed by the authors, indicating that positronium emerges from the powder grains into the voids.
Journal ArticleDOI
Hyperfine constants for the ethyl radical in the gas phase
Paul W. Percival,Jean-Claude Brodovitch,Siu-Keung Leung,Dake Yu,Robert F. Kiefl,David M. Garner,Donald J. Arseneau,Donald G. Fleming,Alicia C. Gonzalez,James R. Kempton,Masayoshi Senba,Krishnan Venkateswaran,Stephen F. J. Cox +12 more
TL;DR: In this article, the authors used level-crossing spectroscopy to measure the muon, proton, deuteron, and 13C hyperfine coupling constants for the isotopically substituted ethyl radicals CH2CH2Mu, CD2CD2Mu and 13CH213 CH2Mu in the gas phase.
