Abstract Single-electron detachment (SED) cross sections for Cr^- and Ti^- in collision with N₂ have been obtained in the energy region of 10-30keV, for the first time to our knowledge. In the present energy range, the magnitude of the Cr^-+N₂ and Fe^-+N₂ SED cross sections is larger than that of Cu^-+N₂. It is also found that the cross sections for Cr^- and Ti^- in collisions with N₂ exhibit different dependences on anion impact velocity from that of Cu^-
