Electron detachment of negative ions, in collision with a
static gas target, is known to be one of the most fundamental
processes occurring in negative-ion-atom collisions. The
experimental results of cross-section data for transition element
ions in collision with gases are of great interest not only for
their potential application value, but also as a challenge to a
theoretical study of complex negative ions in collision with
atoms or molecules. In the present work, the single-electron
detachment (SED) cross-sections for and
in collision with , have been
obtained in the energy region of 10-30
. By using a
single-particle detector for both neutral atoms and ions, the
experimental uncertainty of the results is improved in this work.
