Abstract

Depletion of FeO in the interstellar medium through resonance states of FeO− was studied through collision-induced dissociation of FeO−. Collisional excitation of FeO− lead to the yield of Fe− and O−, with a higher yield for Fe−. The ground electronic state of FeO− was identified to be 6Δ state and the results are compared with previous theoretical and experimental results. The kinetic energy distributions of the fragments revealed two FeO− anion resonances accessed upon excitation and their potential energy curves were evaluated. The role of the observed resonances in the depletion of FeO and the viable presence of Fe− and O− in Sagittarius B2 are discussed.
