title: Superelastic collisions of electrons with excited Mn(+).
abstract: Excited Mn(+) ions formed by electron ionization of Mn2(CO)10 are deexcited in superelastic electron-ion collisions. The ions are held in the trap of a Fourier transform ion cyclotron resonance spectrometer and subjected to bombardment by an electron beam of varying energy. The population of excited Mn(+) ions after exposure to the beam is monitored by examining reaction of the trapped Mn(+) ions with Cr(CO)6. Charge transfer to form Cr(CO) 6 (+) is exothermic and efficient only for excited Mn(+). It is found that deexcitation is read if y observable for electrons with energies less than 2 eV.
