 Abstract: The thesis at hand deals with the influence of the lepton spin on the rates for e+e- pair production by a nucleus in an intense laser eld. The process of pair production is considered to be a Coulomb-induced transition from a Volkov state with negative energy to a Volkov state with positive energy, according to the Dirac theory. Starting with the transition amplitude for this process the pair production rates are calculated, taking di erent numbers of absorbed photons from a circularly polarized laser wave into account. Our calculations reproduce the well-known results for the spin-resolved single photon process.Beyond that we discover that the e ffect arising from polarization of the produced particles is not necessarily increased by absorbing more photons. In fact the energy transfer to the produced particles is identi ed as the main impact on their polarization. An efficient transfer of helicity becomes possible in the transition regime. Results for total and differential rates are going to be presented. The results for the considered processes are discussed with respect to the possibility of their experimental implementation.
