Negative Ion Electron Photodetachment from a Near-Blackbody Photon Source

Negative Ion Electron Photodetachment from a Near-Blackbody Photon Source

We have observed the rapid loss of nitroxide anion (3NO-) in a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR). The loss arises from two effects:  a pressure-dependent component consistent with collisional electron detachment from 3NO-, and a pressure-independent loss that we at...

Zusammenfassung:We have observed the rapid loss of nitroxide anion (3NO-) in a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR). The loss arises from two effects:  a pressure-dependent component consistent with collisional electron detachment from 3NO-, and a pressure-independent loss that we attribute to direct (bound-free) photodetachment induced by light emission from a heated filament inside the cell.
