Description
delta-electron emission from superheavy quasiatomic systems formed during heavy-ion collisions was studied for several systems with united atomic charge Z/sub u/ up to 171. The double differential cross sections d2sigma/dE/sub e/dΩ/sub e/ including the cross sections for total electron emission, electron emission from 1s/sub 1/2/ and 2p/sub 1/2/sigma states of the quasiatom, and the electron emission probabilities P(R0) for total electrons as well as for K-shell electrons are presented. These results are compared with available theoretical results. The results are interpreted in terms of the relativistic localization of the electronic wave functions and the effects due to the increase of the electronic binding energy. Binding-energy differences between K- and L-shell electrons are given for all the systems studied
