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.
