Probing anion resonances in FeO−: a species of astrophysical relevance

Synopsis We report the first experimental probe on resonance states in FeO anion, a molecule of astrophysical relevance. Excitation of FeO− through collision with argon was performed to measure the kinetic energy release in the centre of mass frame. Results show access of two anion resonances upon c...

Description
Summary:Synopsis We report the first experimental probe on resonance states in FeO anion, a molecule of astrophysical relevance. Excitation of FeO− through collision with argon was performed to measure the kinetic energy release in the centre of mass frame. Results show access of two anion resonances upon collisional excitation. We discuss our evaluation of these two resonances from kinetic energy release in the centre of mass frame. The astrophysical importance of these anion resonances will be presented.
