Investigating anion dissociation dynamics with ion momentum imaging
  Molecular Physics seminar

Tuesday 04 June 2013
from 14:00 to 15:00
at FB41
Speaker : Mike Fogle (Auburn University, Alabama, USA)
Abstract : Ion momentum imaging is used to study the dynamics of CO_2 and N_2O upon dissociative electron attachment (DEA). The assignment of attachment states and the resulting dynamics have been debated for these systems for the last 30 years. Our new apparatus at Auburn University can measure the three dimensional momentum distribution of O- dissociation fragments and, with the help of new theoretical calculations performed by our collaborators at Lawrence Berkeley National Laboratory, we can assign the associated attachment state of the difference DEA resonances as well as explain the complex dynamics that occur upon formation of the transient negative ion.
