J/A+AS/109/193 IRON project VIII. Ti-like ions (Berrington, 1995)
Atomic data from the IRON project. VIII. Electron excitation of the 3d4 5DJ ground state fine-structure transitions in Ti-like ions V II, Cr III, Mn IV, Fe V, Co VI and Ni VII Berrington K.A. <Astron. Astrophys. Suppl. Ser. 109, 193 (1995)> =1995A&AS..109..193B (SIMBAD/NED Reference)
Keywords: atomic data ADC_Keywords: Atomic physics Description (Abstract): Electron excitation collision strengths for the 3d4 5D(J-J') ground term fine-structure transitions in titanium-like ions V II, Cr III, Mn IV, Fe V, Co VI and Ni VII are calculated using R-matrix techniques. The model target ion includes all 3d4 terms, and the low-energy collision strengths are dominated by autoionizing resonances. The collision strength is averaged over a Maxwellian velocity distribution to obtain effective collision strengths as a function of electron temperature. To our knowledge, these are the first published data for these processes. File Summary:
