Electron correlation in fast ion-impact single ionization of helium atoms
Electron correlation in fast ion-impact single ionization of helium atoms |
| Fig.#cod#x00A0;2. Present FDCS calculated for single ionization of helium by 75-keV protons in the scattering plane are compared with their measured values as well as their corresponding values obtained from other theories. The electron emission energy and the transverse momentum transfers are the same as in Fig.#cod#x00A0; 1 . The present results are obtained using the Byron#cod#x2013;Joachain wave function for helium targets. Solid lines: FBA-2CW. Dashed lines: 3DW calculations multiplied by 0.2#cod#x00A0;0.13#cod#x00A0;a.u., 0.3#cod#x00A0;0.41#cod#x00A0;a.u., and 0.6#cod#x00A0;0.73#cod#x00A0;a.u., respectively. Dash-dotted lines: 3CW calculations multiplied by 0.35#cod#x00A0;0.13#cod#x00A0;a.u., 0.55#cod#x00A0;0.41#cod#x00A0;a.u., 1.18#cod#x00A0;0.73#cod#x00A0;a.u., and 2#cod#x00A0;1.38#cod#x00A0;a.u., respectively. Dotted lines: CDW-EIS. Solid circles are for experimental data. |
