Nondipolar corrections to the photoelectron angular distributions from C-60 have been calculated for the highest occupied molecular orbital ( HOMO), HOMO-1, and HOMO-2 photoemission bands. The computational method employed takes advantage of a parallel algorithm that uses a multicentric expansion of bound- and scattering-wave functions and a density-functional theory one-particle Hamiltonian. First-order nondipolar asymmetry parameters have been calculated from thresholds of up to 160 eV of photon energy. Strong oscillations, reminiscent of those found in the ratio of the HOMO and HOMO-1 partial cross sections, have been observed in the nondipolar asymmetry parameters as well. The oscillations have the same period, but a different phase, compared to the ones that characterize the HOMO-HOMO-1 intensity ratio.

Nondipolar effects in the photoionization dynamics of carbon tetrafluoride Toffolı, Danıele; Decleva, Piero (American Physical Society (APS), 2008-12-01) The linear combination of atomic orbitals approach to the calculation of the molecular continuum spectrum with B-spline basis functions has been applied to the calculation of the first-order nondipolar corrections to the photoelectron angular distributions from carbon tetrafluoride. Dipolar and nondipolar asymmetry parameter profiles have been calculated for every single-particle orbital ionization. A comparison with the available experimental data gives good agreement for the dipolar asymmetry parameter. N...
BOUND-STATE ENERGIES FOR THE EXPONENTIAL COSINE SCREENED COULOMB POTENTIAL IKHDAIR, SM; Sever, Ramazan (Springer Science and Business Media LLC, 1993-09-01) The energy eigenvalues of bound states of an electron in the general exponential cosine screened Coulomb potential are obtained using the shifted 1/N expansion method. The energies for the states from 1s to 8k are calculated from six to eight significant figures. The energy eigenvalues for the 1s, 2s - 2p, 3s - 3d, and 4s - 4f states are also presented as a function of the screening parameter lambda. Results are compared with the ones obtained by other workers. The agreement reduces roughly for large lambda...
Step-up and Step-down Operators of a Two-Term Molecular Potential Via Nikiforov-Uvarov Method Arda, Altug; Sever, Ramazan (Springer Science and Business Media LLC, 2014-04-01) The creation and annihilation operators of a two-term diatomic molecular potential are studied and it is observed that they satisfy the commutation relations of a SU(1,1) algebra. To study the Lie algebraic realization of the present potential, the normalized eigenfunctions and eigenvalues are computed by using the Nikiforov-Uvarov method.
Exact Pseudospin Symmetric Solution of the Dirac Equation for Pseudoharmonic Potential in the Presence of Tensor Potential AYDOĞDU, OKTAY; Sever, Ramazan (Springer Science and Business Media LLC, 2010-04-01) Under the pseudospin symmetry, we obtain exact solution of the Dirac equation for the pseudoharmonic potential in the presence of the tensor potential with arbitrary spin-orbit coupling quantum number kappa. The energy eigenvalue equation of the Dirac particles is found and the corresponding radial wave functions are presented in terms of confluent hypergeometric functions. We investigate the tensor potential dependence of the energy of the each state in the pseudospin doublet. It is shown that degeneracy b...
Geometric measures of entanglement UYANIK, KIVANÇ; Turgut, Sadi (American Physical Society (APS), 2010-03-01) The geometric measure of entanglement, which expresses the minimum distance to product states, has been generalized to distances to sets that remain invariant under the stochastic reducibility relation. For each such set, an associated entanglement monotone can be defined. The explicit analytical forms of these measures are obtained for bipartite entangled states. Moreover, the three-qubit case is discussed and it is argued that the distance to the W states is a new monotone.
