Separation of ions with the same charge to mass ratio from a collision experiment [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.
