1Two-electron QED Studies for Helium-like Uranium显示文摘The study of structure of few-electron heavy ions is of important interest due to the strong field effects. Helium-like ions are the simplest atomic multi-body systems. A considerable improved precision has been made in both theory and experiments recently. The experiment exploits the radiative recombination (RR) transitions into the vacant 1 s shell of bare and H-like ions. In this process, the energy carried by the emitted photon is the energy difference between the initial and final electron state, hω=Ekin+EB.

2Exclusive Population of n=2 S-states in He-like Uranium by Ionization Process显示文摘K-shell ionization for Li-like uranium ions in collisions with a N2 target was performed at the ESR storage ring. We found surprisingly that in such close encounters the 2 s electron remain almost unaffected by the collisions. A dedicated experimental study was conducted by using Li-like uranium ions at an initial energy of 378 MeV/u in order to manifest the situation. In Fig.1 a typical spectrum is shown registered by a Ge(i)Ma Xinwen D.Banas Th.Sthlker H.F.Beyer F.Bosch A.Br(?)uning-Demian A.Gumberidze S.Hagmann C.Kozhuharov P.H.Mokler R.Mann A.Orsic Muthig D.Sierpowski U.Spillmann S.Tachenov Z.Stachura A.Warczak 2002近代物理研究所和兰州重离子加速器实验室年报:英文版2002,,1:0
3Polarization Measurements in Radiative Electron Capture into High-Z Ions显示文摘Recently, there has been great interest in the linear polarization of photons produced by radiative electron capture (REC, the time reversed photoionization in ion-atom collisions). No such data are available for the high-Z regime till now. By using high efficiency by by a new generation of segmented germanium detectors that have energy as well as position resolution this field can be investigated experimentally.
