Phys. Rev. A 72, 032715 (2005) [8 pages]Electron-impact ionization of hydrogen and lithiumlike systemsReceived 21 June 2005; published 14 September 2005 The electron impact single ionization cross sections on a number of targets with atomic number Z=1–92 in the H and Li isoelectronic sequences are calculated using a modified version of the recently propounded relativisitic improved binary-encounter dipole (MRIBED) model [ M. A. Uddin et al. Phys. Rev. A 70 032706 (2004)]. The modified RQIBED (MRIBED) model along with a Z-dependent factor in it is found remarkably successful in the applications to H- and Li-like systems and also valid for the ionization of a filled s orbit including the He-like targets. © 2005 The American Physical Society URL:
