Abstract
Absolute cross sections for He II (n = 4 --> n = 3) visible light emission subsequent to charge changing collisions (0.8-9.75 keV amu-1) of He2+ with Li have been measured. The respective l state selective He+(4l) electron capture cross sections have been determined from the intensity of the He II (n = 4 --> n = 3) transition along the ion beam path by means ot a deconvolution technique based on the lifetimes of the He+(4l) states.
