Abstract Dynamical and spontaneous positron emission are investigated for heavy-ion collisions with long time delay using a semiclassical description. Numerical results and analytical expressions for the characteristic quantities of the resulting spontaneous positron line, i.e., its position, width, and cross section, are compared. The expected behaviour of the line position and cross section and its visibility against the spectrum of dynamically created positrons is discussed in dependence on the united chargeZ u of projectile and target nucleus in a range of systems fromZ u =180 up toZ u =188. The results are confronted with presently available experimental data, and possible implications on further experiments are worked out.
