Differential cross sections for elastic and inelastic positronium-hydrogen-atom scattering
(American Physical Soc, 2001-05-01)
A time reversal symmetric regularized electron exchange model was used to elastic scattering, target elastic Ps excitations and target inelastic excitation of hydrogen in a five state coupled model. A singlet Ps-H-S-wave ...
Molecular design of new P3HT derivatives: Adjusting electronic energy levels for blends with PCBM
(Elsevier B.V., 2014-12-15)
An intensive search is underway for new materials to make more efficient organic solar cells through improvements in thin film morphology, transport properties, and adjustments to the energy of frontier electronic levels. ...
Absence of Cooper-type bound states in three- and few-electron systems
(1998-12-01)
It is shown that the appearance of a fixed-point singularity in the kernel of the two-electron Cooper problem is responsible for the formation of the Cooper pair for an arbitrarily weak attractive interaction between two ...
Spectroscopic study of lanthanide squarate hydrates
(1994-12-01)
In the present investigation some spectroscopic properties of several lanthanide squarate hydrates are reported. The Raman spectra show the same distinctive Jahn-Teller intensity pattern for non-totally symmetric modes, ...
Copolymers with similar comonomers: Tuning frontier orbital energies for application in organic solar cells
(2016-04-01)
Today, there is an intense search for new electron donor polymers for the active layers of organic solar cells. The synthesis of copolymers, in which there is a mix of electron donor monomers with others that are electron ...
Is the decrease of the total electron energy density a covalence indicator in hydrogen and halogen bonds?
(Springer, 2013-05)
In this work, halogen bonding (XB) and hydrogen bonding (HB) complexes were studied with the aim of analyzing the variation of the total electronic energy density H(rb) with the interaction strengthening. The calculations ...
Pauli nonlocality in heavy-ion rainbow scattering: A further test of the folding model
(1997-12-01)
Nonlocal interactions are an intrinsically quantum phenomenon. In this work we point out that, in the context of heavy ions, such interactions can be studied through the refractive elastic scattering of these systems at ...
Dynamics of a collapsing and exploding Bose-Einstein condensed vortex state
(2002-10-01)
The dynamics of small repulsive Bose-Einstein condensed vortex states of 85Rb atoms in a cylindrical traps with low angular momentum was studied. The time-dependent mean-field Gross-Pitaevskii equation was used for the ...
Contribution of the second Landau level to the exchange energy of the three-dimensional electron gas in a high magnetic field
(AMER PHYSICAL SOC, 2008)
We derive a closed analytical expression for the exchange energy of the three-dimensional interacting electron gas in strong magnetic fields, which goes beyond the quantum limit (L=0) by explicitly including the effect of ...
Dynamical calculation of direct muon-transfer rates from thermalized muonic hydrogen to C6+ and O8+
(2000-08-01)
Moun-transfer reactions from muonic hydrogen to carbon and oxygen nuclei employing a full quantum-mechanical few-body description of rearrangement scattering were studied by solving the Faddeev-Hahn-type equations using ...
