The decay of 2~~R n l z 3 to levels in 2~~A t l , , .The decay of zo9Rn to levels in 209At has been investigated. Gamma rays were studied in singles and coincidences using Ge(Li) detectors. Conversion electrons were recorded with a Si(Li) detector. A decay scheme is suggested, indicating electron capture branches to positive parity states at 1 954, 2 136 and 2 415 keV. These states are interpreted in terms of core excitations in conformity with the ,07Bi isotone. Two levels at 408 and 746 keV, tentatively assigned spin 7/2-, are fed by electron capture with logfr values of 6.8 and 6.4, respectively.
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.
