Double electron capture in relativistic U92+ collisions observed at the ESR gas-jet target

Processes associated with double electron capture into bare U92+-ions have been observed under single collision conditions, Regions of very low cross sections, close to mbarn, have been explored successfully In particular, an attempt to register photons with twice the energy of single K-REC photons has been performed. Moreover, K-REC spectra associated with double charge e xchange have been analysed in terms of their angular distribution. As a res ult, evidence for correlated electron capture has been found.
