Bound–free pair creation with simultaneous capture of the electron in relativistic collisions of highly charged ions — •Anton Artemyev1, Benasser Najjari2, Andrey Surzhykov1, and Alexandr Voitkiv2 — 1Universitaet Heidelberg, Germany — 2MPI-K Heidelberg, Germany
During recent years some experimental and theoretical interest has arised to the studies of negative-continuum dielectronic recombination (NCDR) [1], which is new mechanism of electron–positron pair creation. For the experimental investigation of this process it is important to know all competitive processes which also yeld the change of the projectile charge by two units and a positron. Therefore in our contribution we discuss possible competitive processes. For example, we analyze the radiative and non-radiative capture of the target electron with simultaneous bound-free pair creation. Cross-sections of these processes are compared with NCDR ones.
