Collisional detachment in oxygen was studied for pressures of about 20-60 Torr and with mass analysis which also allowed conversion rates to be calculated. For O<sup>-</sup>, delta <sub>1</sub>/N (detachment coefficient/gas density) was found to be about 5*10<sup>-18</sup> cm<sup>2</sup> at E/N (field strength/gas density) of about 50 Td where for O<sub>2</sub><sup>-</sup>, delta <sub>2</sub>/N approximately 1*10<sup>-18</sup> cm<sup>2</sup>. The need for an accurate measurement of the conversion rate for O<sup>-</sup> to O<sub>2</sub><sup>-</sup> is emphasized.
