[en] The DA processes of O- ions in NO and O2 are investigated using a 60° sector field mass spectrometer. In NO O- appears at (7.43+/-0.2) eV and the analysis of the DA curve indicates the probable existence of two other processes at 8.1 eV and 9.0 eV. In O2 only one process is observed at (3.45+/-0.3) eV. For both molecules an attempt is made to establish the shape of the potential energy curve of the electronic states of the transient negative molecular species involved.
