    Notes: Abstract A formulation of stripping reactions into the continuum is given taking the(d, p)-reaction as a specific example. We use the DWBA and the assumption that contributions from the nuclear interior are negligible. Under these assumptions we show that the cross section can be split into a “distortion matrix element” and a term depending on the neutron target interaction only through the phase shifts of the corresponding elastic neutron scattering. The interference with the “pure break-up” process is discussed. The connection between stripping to bound and unbound states in the limit of zero binding energy is established. A comparison with recent experimental results is given, where the “distortion matrix elements” are calculated, for the sake of simplicity, in the “Butler approximation”.

    Notes: Abstract Electron screening effects influence the classical trajectory of the projectile. The influence of this effect on inner shell ionization probabilities is studied. We compare calculations with straight lines trajectories to trajectories in a screened and in an unscreened Coulomb potential. Rather simple prescriptions are found which allow to take the screening effects into account using “modified Coulomb trajectories”. Their accuracy is investigated and demonstrated for a number of representative examples.

    Notes: Abstract Light ion induced alignment measurements ofL 3-subshell in heavy atoms are analyzed within the framework of the semiclassical theory of inner shell ionization. Coulomb deflection effects are exactly taken into account by hyperbolic classical orbits while the electron in the initial and final states is approximated by screened relativistic hydrogenic wave functions. Satisfactory agreement between experiments and theory is obtained for proton- and α-particle induced reactions within the whole region of bombarding energies.
