Differential Cross Sections for Single and Multiple Ionization in 3.6 AMeV Cr7+ and Cr20+ + Ar Collisions — •M. Nofal1,2, S Hagmann3,2, C. Kozhuharov2, R. Moshammer1, and N. Lineva21Max Planck Inst. f. Kernphysik, Heidelberg — 2GSI-Darmstadt — 3Inst. f. Kernphysik, Univ. Frankfurt

We have investigated single and multiple ionization of Ar using 3.6AMeV Cr7+ and Cr20+ beams from the UNILAC. The perturbation strength characterized by the Sommerfeld parameter q/v varied between 0.6 and 1.7. Electrons and recoil ions emitted in the collision were momentum analyzed using a reaction microscope. We present differential cross sections as a function of electron and recoil longitudinal momentum for a number of electron multiplicities. We compare data with cross sections [1] derived for Ar ionized with strong perturbations q/v=4.4.
