Electron Attachment to Cl₂O — •Wolfgang Sailer¹, H. Drexel¹, V. Grill¹, P. Tegeder², N.J. Mason², P. Scheier¹, and T.D.

Using a recently improved trochoidal electron monochromator in conjunction with a quadrupole mass spectrometer we have measured electron attachment cross sections for Cl₂O in the energy range from 0 up to 10 eV.

Besides the parent anion we have also studied and detected the following fragment ions: Cl⁻, ClO⁻, Cl₂⁻ & O⁻. The present study allows to clarify previous discrepancies in the literature.

Other gases also under study in our laboratory at present include Cl₂ and SF₅CF₃.
