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. For bareMaXinwen Th.Stoehlker A.Gumberidze H.F.Beyer G.Bednarz F.Bosch CaiXiaohong S.Fritzsche S.Hagmann C.Kozhuharov O.Klepper D.Liesen P.H.Mokler D.Sierpowski Z.Stachura M.Steck A.Surzhykov S.Toleikis A.Warczak Y.Zou 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
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.

4Resonant Transfer and Excitation Study for Hydrogen-like Uranium Ions显示文摘He-like ions are the simplest atomic system where the electron-electron interactions can be studied without any disturbance by further correlations. For heavy atomic systems the structure and dynamics differ significantly from those of light ions, and in this relativistic domain the current or magnetic interactions play anP.H.Mokler G.Bednarz F.Bosch A.Gumberidze S.Hagmann C.Kozhuharov D.liesen U.Popp D.Sierpowski Z.Stachura Th.Sthlken S.Tashennov S.Toleikis A.Warczak 2001IMP & HIRFL Annual Report2001,,1:0
