Dissociative electron-attachment cross-section measurements for the production of H/sup -/ and Cl/sup -/ from HCl have been performed with use of a crossed target-beam--electron-beam collision geometry and a quadrupole mass spectrometer. The relative-flow technique is employed to determine the absolute values of cross sections. The attachment energies corresponding to various cross-section maxima are 7.1 +- 0.1 eV and 9.05 +- 0.1 eV for H/sup -//HCl; 0.85 +- 0.02 eV for Cl/sup -//HCl. The cross sections at these maxima are 2.07 x 10/sup -18/ cm/sup 2/ and 0.93 x 10/sup -18/ cm/sup 2/ for H/sup -//HCl; 26.59 x 10/sup -18/ cm/sup 2/ for Cl/sup -//HCl, respectively.
