Abstract
Spectra of detached electrons produced in mutual collisions of D− ions in the relative energy range of 1.8−6.1 eV were investigated. In addition to electrons corresponding to conversion of D− ions into D0 atoms, peaks corresponding to the production of D2 molecules and D −2 molecular ions in the ground electronic state were revealed. The existence of D −2 ions over a time longer than the period of molecular oscillations was confirmed experimentally for the first time.
