Inner-shell x-ray production in adiabatic iodine -Z 2 collisions withZ 1+Z 2≧100

For heavy collision systems withZ _UA ≧100 the excitation mechanism for electrons in molecular orbitals from 2p _{1/2 1/2} up to 3d_{3/2 1/2}, which end up inK andL levels of the collision partners, is investigated for Iodine projectile velocityv between 1.3 and 3.7 a.u. (i.e. 6.3 MeV≦E _i ≦45 MeV). For 2p _{1/2 1/2} excitation a prevailing radial coupling excitation mechanism is found. In a two state approximation coupling strengths are derived for decisive isolated crossings; for the strong variation of the projectileL x-ray spectra with targetZ and impact velocity a Landau Zener type model is suggested.
