One- and two-body dissipation in peripheral heavy ion collisions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

For peripheral collisions of heavy ions we solve the many-body Schrödinger equation in second order time-dependent perturbation theory. The two nuclei interact via a two-body interaction of finite range. With controllable approximations we get to a sensible comparison between 1p−1h excitations caused by the coherent Hartree part and direct 2p−2h excitations both created by the same two-body interaction. The results of the calculation show that for peripheral collisions almost all excitation energy originates from one-body dissipation. Furthermore we encounter large virtual excitations during the collision indicating a non Markovian process.
