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.
