Abstract : The rate coefficient for the two-body attachment to O3 of 300K electrons has been measured. The attachment coefficient increases rapidly with increasing electron energy at characteristic electron energies of 0.3 eV. Measurements in pure O3 also show that the attachment process is directly porportional to pressure for pressures between 0.5 and 2 Torr, as expected for a dissociative attachment process. Unsuccessful attempts to detect electron detachment in collisions of O3(-) and CO3(-) with O3 suggest an upper limit to the rate coefficient for this process. (Author)
