δ-electron emission in superheavy quasiatomic systems with total chargeZu=110 to 171

δ-electron emission from superheavy quasiatomic systems formed during heavy-ion collisions was studied for several systems with united atomic charge $Z_u$ up to 171. The double differential cross sections $d^2$σ/${\mathrm{dE}}_e$d${\Omega }_e$ including the cross sections for total electron emission, electron emission from 1$s_{1/2}$ and 2$p_{1/2}$σ states of the quasiatom, and the electron emission probabilities P($R_0$) 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.
