Abstract
The pattern of positively charged fragments from methyl bromide as a result of isomeric transition of 4.4‐hr Br80m has been measured by mass spectrometric techniques. A peaked distribution of charge states of atomic bromine ranging from Br+1 to Br+13 was observed, the most probable being Br+7. The finding of singly, doubly, and triply charged carbon‐containing fragments gives evidence that the CH3Br80 daughter ion breaks apart by Coulombic repulsion of redistributed charges following internal conversion and subsequent Auger electron transitions. Multiply charged polyatomic species produced by the nuclear transition are unstable.Keywords
