Abstract

We present various differential cross sections for the single ionization of Li by O8+ ions. We use a time-dependent, close-coupling approach to model the evolution of a one-active-electron wave function in the field of the incoming projectile for a range of impact parameters. In addition, a Fourier transform approach is used to extract differential cross sections for a specific projectile momentum transfer value. This scheme allows us to incorporate information about the interaction of the two heavy nuclei [the so-called nuclear-nuclear (NN) interaction] and to assess its influence in the differential cross sections. We find noticeable differences in the shape of the differential cross sections when we include (neglect) the NN interaction. Our single-differential cross-section calculation shows excellent agreement with experimental data. In addition, recent measured double-differential cross sections as a function of electron energy and transverse momentum transfer are reasonably well reproduced by our theoretical calculations.
