Abstract:Measurements have been made of the x-rays emitted by mesonic carbon and oxygen atoms formed by the capture of negative cosmic ray tx mesons. A 4-liter tank of liquid scintillator, dioxane, C4O2H8 (plus 10 g/1 of ^>-terphenyl) served as the absorber and as the detector for the stopping of cosmic-ray JJ. mesons. The mesons were identified by the method of delayed coincidences.The mesonic x-rays from the dioxane were detected by a scintillation spectrometer. Spectrometer pulses in coincidence with the stopping me… 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.
