摘要

The production of O- and O-2(-) by dissociative attachment to ozone has been studied as a function of electron energy (from about 0 up to about 9 eV) in a recently constructed high-resolution crossed beams apparatus combined with a quadrupole mass spectrometer. After absolute calibration of the ozone gas density and taking into account the different detection efficiency absolute attachment cross sections for both fragment anions could be deduced. The corresponding peak values are 2.8 x 10(-17) cm(-2) at an electron energy of 1.33 eV and 1.83 x 10(-17) cm2 at an electron energy of 1.05 eV for the O- and O-2(-) production, respectively.
