The 8 -and 9 -distributions of the Kr 7+ -excited states resulting from single-electron capture in Kr 8+ -Li(2s) collisions are determined experimentally for collision energies from 0.1 to 1.0 keV amu −1 . The experimental σ (n ) cross sections are deduced from emission cross sections obtained by means of near ultraviolet and visible photon spectroscopy. In addition, a complete theoretical study of these distributions has been made using the classical trajectory Monte Carlo (CTMC) method for a larger energy domain (0.1-5.0 keV amu −1 ). The theoretical and experimental results are, on the whole, in fair agreement. The results are discussed in terms of dynamical couplings involved in state-selective electron capture from an analysis of electronic energy curves calculated for the Kr 7+ + Li + system.
