Abstract

When using 4 MeV positive muons as a radiation source, the 4 MeV of radiation chemistry that occurs is ignored and attention is focused on the fate of the muon at the very end of its track. On measuring the yields of the various muon-containing products there are seen to be missing fractions, which are compared with geminate yields of radiolysis. Muon studies were made by muon-spin-rotation and level-crossing-resonance techniques. The former gives information about muonium atoms only if they form in less than a nanosecond and live for more than a microsecond, whereas the latter technique allows any muonated free radical present as the muon decays to be studied. The latter is used here to determine the formation rate of a product-specifically the radical formed from addition of muonium to acetone.
