Abstracts
Preliminary data on 1300 decays in magnetically-shielded emulsions exposed to the Chicago synchrocyclotron are consistent with an angular distribution W() = 1 - 0.12 cos . The formation of "muonium'' (+ e-) may be an important cause of depolarization in such experiments. (Science Abstracts, 1957, 5643. K. H. Barker.).
