Electron Impact Excitation of Single 105Db, 106Sg, 107Bh, 108Hs, 109Mt, 110Ds, 111Rg, 112Cn, 113Uut, 114Fl, 115Uup, 116Lv, 117Uus, 118Uuo Atoms O Subshell Ionization Cross Sections by Using Lotz's Equation

O shell and five O subshells ionization cross sections (-so and croiti = following electron impact on single (105llb, to118Uuo)atoms calculated. By using Lotz's equation in Matlab ionization cross section values obtained for 14 electron impact energy values in first ionization energy to five times ionization energy range for each atom. Lotz's parameters and special commands used for each ionization cross sections calculations. Starting all most from ionization threshold values; ionization cross sections are increasing rapidly with electron impact energy E0. For higher E. values this increments getting smaller for every 0subshells. For smaller Eoenergy close to threshold all ionization cross sections decrease. For a fixed electron impact energy while 7, value increases from 105.7<118; ionization cross sections decrease with Z. Results may help to understand similar findings which obtained from other electron impact excitation of Oi subshells ionization cross sections studies for similar size single atoms.
