Abstract

The positron production yields in close ion-atom collisions have been investigated for the U+Cm, U+U and U+Pb scattering systems at U beam energies between 4.7 and 5.9 MeV/u. Furtheron positron spectra were measured for the overcritical U+U and the undercritical U+Pb system at 5.9 MeV/u and a scattering angle 8 Lab Ion = 45°±10° . All positron yields, including earlier measurements, follow a simple scaling law. No characteristic deviations from this or other signatures indicating level diving for the overcritical U+Cm and U+U systems have been observed within the experimental errors of about 30 %.
