    Following Electron Impact Excitations of Rn, Ra, Th, U and Pu Single Atom L Sub-shells Ionization Cross Section Calculations by Using Lotz's Equation
    (Amer Inst Physics, 2016) Ayinol, M.; Aydeniz, D.
    shell ionization cross section and Li subshells ionization cross sections of Rn, Ra, Th. U, Pu atoms calculated. For each of atoms, ten different electron impact energy values (E0) are used. Calculations carried out by using Lotz equation in Matlab. First, calculations done for non-relativistic case by using non-relativistic Lotz equation then repeated with relativistic Lotz equation. (sigma(L) total and sigma(Li)(i = 1,2,3) subshells ionisation cross section values obtained for E-o values in the energy range of E (Li)<4E(Li) tier each atom. Starting almost from E-o = E-Li values of the each sub shell ionization threshold energy, CTL total and nu 1,2,3) are increasing rapidly with E-o. For a fixed E-o = 3.E-Li), while Z increases from 86<94, (sigma(L), and sigma(Li) (i =1, 2,3) arc decrease. These results will also help to understand some sigma(L)(i = 1,2,3) subshells results obtained from other electron-atom impact studies.

    Following Electron Impact Excitations of Single Os, Pt, Hg, Pb and Po Atom L Subshells Ionization Cross Section Calculations by Using Lotz's Equation
    (Amer Inst Physics, 2016) Aydinol, M.; Aydeniz, D.
    L shell ionization cross section and Li, subshells ionization cross sections of Os, Pt, fig, Pb, Po atoms calculated. For each atom, ten different electron nnpacty energy values E-oi used. Calculations carried out by using nonrelativistic Lutz equation in Matlab. Ionization cross section values obtained for E0, values in the energy range of E Li <= E(oi <=)4E(Li) for each atom. Starting Almost from E-oi, E-Li(i = 1,2,3) values of the each subshell ionization threshold energy, ionization cross section are increasing rapidly with E-oi. For a fixed E-oi= 3. E-Li values, while Z increases from 7, = 76 to 7 = 84 ionization cross section are decrease. These results help to understand some results which obtained from other electron-sigle atom impact studies on sigma(Li) subshells.
