Following Electron Impact Excitation of Single(118Uuo, 119Uu1, 120Uu2, 121Uu3, 122Uu4) Atoms O Subhell Relativistic Ionization Cross Sections by Using Lotz’s Equations

Following electron impact on 118Uuo (Ununoctium), 119Uu1, 120Uu2, 121Uu3, 122Uu4 atoms O shell and five Oi subshells relativistic ionization cross sections σrelO and σrelOi calculated. By using Lotz's equation in Matlab σrelO and σrelOi values obtained for 20 electron impact energy in first ionization energy to 13 times ionization energy range for each atom. Lotz's parameters and special commands used for relativistic σrelO and σrelOi calculations of Oi subshells of each atom. Starting all most from ionization threshold values; ionization cross sections are increasing rapidly with electron impact energy E0. For higher E0 values this increments getting smaller for every Oi subshells. For smaller E0 energy close to threshold all ionization cross sections decrease. For 1000eV fixed impact energy while Z value increases from 118≤Z≤122; 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 atoms
