TY - JOUR A1 - Schlüter, Paul A1 - Soff, Gerhard A1 - Greiner, Walter T1 - Monoenergetic positron conversion in heavy ion fragments T2 - Physical review C N2 - Conversion processes in light nuclei with transition energies above the e+, e- pair creation threshold are investigated within an analytical framework. In particular, we evaluate the ratio of electron transition probabilities from the negative energy continuum into the atomic K shell and into the positive energy continuum, respectively. The possible role of monoenergetic positron conversion with respect to the striking peak structures observed in e+ spectra from very heavy collision systems is examined.
