Abstract:The absorption of stopped negative pions in 133Cs, 93Nb and ~5Sc has been investigated by means of activation technique. The gamma ray spectra of the obtained activities have been measured with a Ge(Li)-spectrometer. The yields of residual radioactive isotopes have been determined. In addition, the yield of the reaction ~33Cs(re-,p)a32I has been determined to be (2.0_+0.8) x 10 -5 per stopped pion. Isomeric yield ratios have been deduced for the isomeric pairs 86,,,gy and 87m, gy. On the basis of the obtained … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
