Observation Of P-Wave Threshold Behavior In Electron Attachment To F2 Molecules, M. Braun, M.-W. Ruf, Ilya I. Fabrikant, H. Hotop

Using the high resolution laser photoelectron attachment method, we demonstrate that the cross section for F- formation due to electron capture by F2 (X1Σg+) molecules at very low energies exhibits p-wave threshold behavior. This finding confirms the theoretical expectation that low-energy attachment to F2 proceeds through the F2-(2 Σu+) p-wave shape resonance in contrast with previous experimental claims for s-wave threshold behavior.


Dissociative Electron Attachment On Surfaces And In Bulk Media, Ilya I. Fabrikant Jan 2007

Dissociative Electron Attachment On Surfaces And In Bulk Media, Ilya I. Fabrikant

Ilya Fabrikant Publications

A theory of dissociative electron attachment to molecules condensed at surfaces and embedded within bulk media is developed. The theory of low-energy electron diffraction is used to obtain the width for electron-molecule resonance scattering in the condensed phase from the width for the gas phase. It is then employed for the calculation of dissociative attachment in the framework of the nonlocal complex potential theory. Specific calculations using the effective mass approximation are carried out for electron attachment to CH3Cl and CF3Cl molecules physisorbed on the surface of a Kr film. The role of image states and ...
