this research has been carried out to study and find a rather general description for a lone pairorbital in molecules. since the orbital parameters must be manageable in advance, and correctgeometry of the molecule (bond lengths) is depend on the appropriate lone pair description; thefsgo method including optimization has been used to obtain orbital parameters and energy. theproposed models for...

The littlest Higgs model with T-parity, which is called LHT model, predicts the existence of the new particles, such as heavy top quark, heavy gauge bosons, and mirror fermions. We calculate the one-loop contributions of these new particles to the top quark chromomagnetic dipole moment (CMDM) ∆K. We find that the contribution of the LHT model is one order of magnitude smaller than the standard ...

Measurements of Rayleigh light scattering and Cotton-Mouton (CM) effect are carried out at room temperature for 100 mM NaCl solutions of apoferritin/ferritin loaded with 0, 90, 100, 500, 700, and 1500 Fe atoms/molecule. Because of the spherical shape, ferritin macromolecule should not manifest magnetic anisotropy; however, in solution it shows the induced magnetic birefringence (CM effect) and ...

016101-1 Many chemically active, hazardous, and toxic substances have a high dipole moment, and they interact strongly with the charged particles and molecular ion clusters. A new nucleation model considering the contribution of the dipole-charge interaction to the ion-induced nucleation rates is developed, with the dipole moment of the condensing monomers as a new parameter. It is shown that i...

We present a simple analysis that allows us to extract the leading mass dependence of the dipole moment of matter fermions that might be induced by new physics. We present explicit results for the supersymmetric model with broken R-parity as an illustration. We show that the extra contributions to the electric dipole moment(edm) of fermions from Rp / interactions can occur only at two loop leve...

We report on differential and integral cross section measurements for the electron impact excitation of the three lowest lying Rydberg bands of electronic states in tetrahydrofuran. The energy range of the present experiments was 15-50 eV with the angular range of the differential cross section measurements being 15°-90°. The important effects of the long-range target dipole moment and the targ...

The energy flow lines (field lines of the Poynting vector) of electric dipole radiation exhibit a vortex structure in the near field when the dipole moment of the source is in circular rotation. The spatial extend of this vortex is smaller than a wavelength and may not be observable by a measurement in the near field. We show that the rotation of the field lines close to the source affects the ...

A search for the electron electric dipole moment d, is carried out with two counterpropagating beams of ground-state 'Tl. The experiment employs atomic-beam magnetic resonance with separated oscillatory fields combined with laser state selection and fluorescence detection. Extensive tests were made for possible systematic effects. The result for the atomic electric dipole moment is d, =(1.6+'5....

The charge-density distribution in 2H-chromene-2-thione (2-thiocoumarin), C(9)H(6)OS, has been determined from X-ray diffraction data measured at 90 K using a CCD detector, to a resolution of sintheta/lambda < 1.08 A(-1). A multipolar-atom density model was fitted against 6908 reflections with I > 2sigma(I) [R(F) = 0.021, wR(F) = 0.022, goodness of fit = 1.81] in order to generate the differenc...
