Electron Impact Inner-shell Ionization of Ions

Electron impact ionization cross-sections (EIICS) for H to Sc isoelectronic series over incident energies ranging from threshold to 10 keV have been reported. Recently we have proposed various [1-3] easy-to-use models for total EIICS of ions. The selection of the range of atomic number $Z $for different isoelectronic series was guided by the availability of the experimental and the quantum calculated EIICS. These models agree well with the experimental results.\\[4pt] [1] A. K. F. Haque, M. A. Uddin, M. Shahjahan, M. R Talukder, A. K. Basak and B. C.
