Experimental Study of Single and Double Electron Detachment Cross Sections for Cl^- in Collision with He

Single-electron detachment （SED） and double-electron detachment （DED） for chlorine negative ions in collision with helium are investigated in the energy region of 5-30 keV （SED） and 5-19 ke V （DED） by growth rate method, respectively. Experimental data from this work are compared with the previous reported data, and a general discussion is given.

Single-Electron Detachment Cross Sections for Transition-Element Negative Ions Ti^-, Cr^-, Cu^- in Collision with N2

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^-.
