The mechanism of formation of muonium atoms from positive muons was studied here through measure- ments of the yield of diamagnetic muon states in dipolar aprotic solvents and for scavenger solutions in hexane and methanol. The results are compared w

Studies of the yields of muonium atoms and diamagnetic-species in hexane in the presence of added scavengers have shown, unequivocally, that muonium is not formed by the “delayed” (microsecond) mechanism proposed recently. Instead, the lifetimes

The rates of reaction of muonium atoms with solutes, ionic and organic, were studied in solvents of wildly differing polarities (water, methanol, and hexane) and their rate constants were compared, where possible. In these reactions which are thos

Experimental studies of excess electrons in aqueous glasses and crystalline ice are reviewed. Emphasis is placed on studies of the two main optical absorption bands, the well known visible band, which is similar to that of the solvated electron in wa

Muonium atoms add to the O atom of the carbonyl group of acetone to give the muonated free radical (CH3)2Ċ-O-Mu when the reaction takes place in water or hydrocarbons, but not when the acetone is localized in micelles. Micelles have no effect on the

In experiments on the pulse radiolysis of crystalline D2O ice at a nominal temperature of 6 K, yields of e−vis, e−ir and the OD radical have been measured as a function of accumulated dose. The yield of e−ir shows a large effect of dose, increa

When samples of trapped electrons in 9.5M LiCl and 3.1M MgCl2 aqueous glasses at 77 K were bleached by single pulses of 694 nm light from a Q‐switched ruby laser, infrared absorption was produced, and luminescence observed in the near ultraviolet a
