    • BEYOND-THE-DIPOLE EFFECTS IN STRONG-FIELD P HOTOIONIZATION USING SHORT INTENSE LASER PULSES 

      Jobunga, Eric Ouma; Kulke, Elmar; Saenz, Alejandro; Ivanov, Mikhail; Bachau, Henri (Humboldt-Universität zu Berlin, 2016-11-03)
      The development of free-electron lasers and new generation light sources is enabling therealisation of high intensities and short pulse durations exceeding the currently attain-able∼1023W cm−2 and atto second time scale ...

    • Partitioning of the Electron Correlation Energy 

      Jobunga, Eric Ouma (arXiv preprint arXiv, 2017-08-14)
      Electron-electron correlation forms the basis of difficulties encountered in many-body problems. Accurate treatment of the correlation problem is likely to unravel some nice physical properties of matter embedded in this ...

    • Partitioning of the Electron-Electron Interaction 

      Jobunga, Eric Ouma (New Horizons in Mathematical Physics, 2020-06)
      Electron-electron correlation forms the basis of difficulties encountered in many-body problems. Accurate treatment of the correlation problem is likely to unravel some nice physical properties of matter embedded in this ...

    • Positron impact excitation of lowest autoionizing state of potassium atom using distorted wave method with absorption and polarization potentials 

      William, Noah Nzeki; Jobunga, Eric Ouma; Singh, Chandra Shekhar (IOP Publishing, 2021-02-25)
      Differential and integral cross-sections, aswell as the alignment and lambda parametersfor positron impact excitation of the lowest autoionizing state of potassium atom, have been calculated using a non-relativistic distorted ...

    • Pseudopotential for Many-Electron Atoms 

      Jobunga, Eric Ouma (Journal of Advances in Applied Physics, 2020-05)
      Electron-electron correlation forms the basis of difficulties encountered in multi-electron systems. Accurate treatment of the correlation problem is likely to unravel some nice physical properties of matter embedded in ...

    • Symmetry-dependent analytical all-electron potential for helium atom 

      Jobunga, Eric Ouma (Elsevier, 2022-09-01)
      Electron–electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron systems are the simplest many-body systems in nature. The Schrödinger ...
