L-subshell ionization cross sections of Au and Bi induced by C"+ and 0'+ ions have been measured for impact energies ranging from 0.25 to 0.79 MeV/u. The data have been compared with the predictions of the ECPSSR [perturbed-stationary-state (PSS) theory with energy-loss (E), Coulomb deflection (C), and relativistic corrections (R)] theory. Reasonable agreement between theory and experiment is observed for the L&(2s&&2) and L3(2p3/2) subshells. For the L&(2p&z&) subshell, however, large disagreement between the data and the ECPSSR predictions persists. This difference could be due to the "collision-induced intrashell" mechanism that was suggested by Sarkadi and Mukoyama [J. Phys. B 14, L255 (1981)].PACS number(s): 34.50.Fa

“…The publications on inner‐shell ionization showed a significant increase per annum since 19602, 3. To update this data, Paul and co‐workers4–12 appear also to be characterized by a rapid increase in their amount. In his 1984 analysis8, Paul used some 3200 cross sections from the literature for protons.…”

The ligand dibenzo[c,g]fluorenide (Dbf(-)), combines a cyclopentadienide ligand and 1,1'-binaphthyl fragment in one molecule. Preliminary investigations confirmed the special electronic situation in this 6pi-electron donor by way of a series of novel transition-metal complexes. Herein, the electron delocalization was investigated in detail by means of DFT calculations in combination with calculations on the nucleus-independent chemical shifts (NICS). These results clearly prove that the Dbf(-) ion gains the largest aromatic stabilization among all benzannulated fluorenides, and there are two almost olefinic C=C bonds in this structure. These bonds undergo cyclopropanation when treated with ZnEt(2) and ClCH(2)I in a modified Simmons-Smith reaction.
