Abstract: The ratio of the charge exchange cross sections for Ba+(5d) and Ba+(6s) on Na, Rb and Cs, for Sr+(4d) and Sr+(5s) on Na and Rb, and for Ca+(3d) and Ca+(4s) on Na have been measured for ion impact energies between 0.5 keV and 30 keV. For the collisions with Na, absolute charge exchange cross section values are derived using data for the resonant process Na + Na+ as a reference. The results are compared to theoretical near-resonance predictions. A method is proposed to study the polarization dependence of the neutralization cross sections for reactions involving ionic D states.
