โฆ Synopsis
A beam of surface muons (4-l MeV) was used to generate thermal&d muonium atoms Or'e-) i;l aqueous solutions.
From m easurements of the muonium atom relaxation time in the presence of various solutes. bimolecuh rate con.stant~ were determined and compred with the correspond&g reactions of the much heavier isotope, the hydrogen atom.

Rate constants have been obtained from the rates of disappearance of the muonium precession signal in aqueous solutions of KMnOa,NaNOa, NaOH, NaCI, HCl, HC104, maleic acid and ethanol.

The flash photolysis of BrOg in presence of 02 gives rise to an absorption band peaking at 260 run. which is assigned to 03. The effect of various additives on this band is explained on basis of competition between the additive. BrOs and 02 on 0 atoms in their 3P ground state. From the analysis of
The decay oi H-atoms in several y-irradiated aqueous solutions was examined by ESR spectroscopy from 'UยฐK to 150ยฐK. In perchloric acid the decay indicates the presence of two trapping sites. The more strongly trapped H-atoms decay by a first-order process, apparently resulting from a slow release fr
