The growth within the physics of highly-ionized atoms because the final NATO backed ASI in this topic in 1982 has been huge, immense. New accelerator amenities able to extending the variety of highly-ionized ions to very high-Z have come on-line or are approximately to be accomplished. We observe fairly the GANIL accelerator in Caen, France, the Michigan country Superconducting Cyclotrons in East Lansing either one of that are presently working and the SIS Accelerator in Darmstadt, FRG that's scheduled to speed up beam in past due 1989. development i~ low-energy ion creation has been both dramatic. The Lawrence Livermore Lab EBIT equipment has produced neon-like gold and there was endured development in ECR and EBIS assets. The medical advancements during this box have stored velocity with the technical advancements. New theoretical equipment for comparing relativistic and QED results have made attainable highly-precise calcula­ tions of power degrees in one-and two-electron ions at high-Z. The calculations are in accordance with the MCDF procedure and the variational process and should be topic to rigorous experimental assessments. at the experimental part, precision x-ray and UV measurements have probed the Lamb shift within the one and electron ions as much as Z=36 with expanding precision.

A change in the orientation of R. Extensive investigations [9] have shown that the rotational motion is of only minor importance in the processes leading to ionization of strongly bound states and to pair production in collision systems with Zu > 137. The reason is that these processes involve almost exclusive quasimolecular states with angular momentum J' = in the united atom limit R -4 0, which have a spherically symmetric density distribution in this limit. On the other hand, numerical calculations have revealed that a very large number of such states must be retained in the coupled equations 28 in order to achieve convergence [10].

Some model calculations have hinted at the possibility of much longer reaction times in collisions of strongly deformed nuclei right at the Coulomb barrier [18]. ] That a delay in the collision due to a nuclear reaction can lead to observable modifications in atomic excitation processes was recognized more than twenty years ago (for the history and an overview of the field see [20]). Early investigations were primarily concerned with light ion reactions, because extrem~ly long delay times can occur there in the case of narrow resonance scattering.
