BS>The pattern of positively charged fragments from methyl bromide as a result of isomeric transition of 4.4hr Br/sup 80m/ was measured by mass spectrometric techniques. A peaked distribution of charge states of atomic bromine ranging from Br/sup +/ to Br/sup 13+/ was observed. the most probable being Br/sup 7+/. The finding of single- double- and triplecharged carbon- containing fragments gives evidence that the CH/sub 3/Br/sup 80/ daughter ion breaks apart by Coulombic repulsion of redistributed charges following internal conversion and subsequent Auger electron transitions. Multiple-charged polyatomic species produced by the nuclear transition are unstable. (auth)
