1-dimensional hamiltonian with ionization energy (ξ) is shown to be exactly the same with the total energy from the standard harmonic oscillator hamiltonian, with the harmonic oscillator potential, mωx/2. Commutation relations for the ladder operators, energy at the n state and the expectation value for the potential are analyzed and shown to be consistent with the principle of ξ. We also deriv...

Cross sections for the removal of both electrons of the hydrogen molecule by two photons are presented at 30 eV photon energy using the time-dependent close-coupling method. Our approach allows detailed information about the dynamics of the ionization process to be extracted, including angular distributions for the outgoing electrons. Analysis of our calculations reveals some similarities to th...

Chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. These concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������Where I is the ionization energy and A is the electron affinity. In thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute el...

We investigate the possible reasons for the discrepancy between the theoretical two-photon ionization cross section, ∼10−56 cm4 s, of Ne8+ obtained within the perturbative nonrelativistic framework for monochromatic light [S. Novikov and A. Hopersky, J. Phys. B 34, 4857 (2001)] and the experimental value, 7 × 10−54 cm4 s, reported in [G. Doumy et al., Phys. Rev. Lett. 106, 083002 (2011)] at a p...
