Abstract
States of doubly charged atomic and molecular ions have been studied b y Threshold PhotoElectrons COincidence (TPEsCO) spectroscopy. This tec hnique involves the detection, in coincidence, of two zero energy elec trons ejected in the photodouble ionisation process. The application o f the TPEsCO technique to rare gases and diatomic molecules is discuss ed. In addition the first observation of the Ar2+(3s(2+)3p(3) nl) sate llite states at threshold is reported.
