| Abstract: | We have studied the electron capture and the target excitation in collisions of Ne+ ions with Li atom by observing the emission spectrum. The emission cross sections of the observed lines and the excitation cross sections of the corresponding states are obtained in the visible region. The relations of the electron capture processes with the energy defect and the ionized potential of the target atom are discussed. The energy range of the Ne+ ions is 20-150 keV. |
