State-selective electron capture in Kr8+-Li(2s) collisions for impact energies from 0.1 to 1.5 keV amu(-1)

The 8l- and 9l-distributions of the Kr7+-excited states resulting from sing le-electron capture in Kr8+-Li(2s) collisions are determined experimentally for collision energies from 0.1 to 1.0 keV amu(-1). The experimental sigma (nl) cross sections are deduced from emission cross sections obtained by me ans of near ultraviolet and visible photon spectroscopy. In addition, a com plete theoretical study of these distributions has been made using the clas sical 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 whol e, in fair agreement. The results are discussed in terms of dynamical coupl ings involved in state-selective electron capture from an analysis of elect ronic energy curves calculated for the {Kr7+ + Li}(+) system.
