چکیده
%'e have applied the Schwinger multichannel formulation [K. Takatsuka and V. McKoy, Phys. Rev. A 24, 2473 (1981)]to the elastic scattering of low-energy (1—30-eV) electrons by silane. Our results, obtained within the fixed-nuclei, static-exchange approximation, are in generally good agreement with recent differential, integral, and momentum-transfer cross-section measurements between 5 and 30 eV. At lower energies, our results reflect the known limitations of the static-exchange approximation. Near the shape resonance, the calculated differential cross section shows significant enhancement at high angles, suggesting an explanation for differences between integral cross sections determined from integrated differential data and those obtained from transmission measurements.

A dressing of a nonspherical potential, which includes n zero range potentials, is considered. The dressing technique is used to improve ZRP model. Concepts of the partial waves and partial phases for non-spherical potential are used in order to perform Darboux transformation. The problem of scattering on the regular X n and YX n structures is studied. The possibilities of dressed ZRP are illus...

A dressing technique is used to improve zero range potential (ZRP) model. We consider a Darboux transformation starting with a ZRP, the result of the " dressing " gives a potential with non-zero range that depends on a seed solution parameters. Concepts of the partial waves and partial phases for non-spherical potential are used in order to perform Darboux transformation. The problem of scatter...
متن کاملTheoretical study of the binding of silane (SiH4) with borane (BH3), diborane (B2H6), and boron trichloride (BCl3): the role of core-electron correlation.
Equilibrium structures and energies of gas-phase molecular complexes SiH(4)···BH(3), SiH(4)···B(2)H(6), and SiH(4)···BCl(3) were determined using second-order Møller-Plesset perturbation theory (MP2) and the aug-cc-pVTZ basis set, with and without explicit core electron correlation. Single-point energies were calculated for the MP2-optimized structures using MP2 with the aug-cc-pVQZ basis set a...

متن کاملHigh pressure studies on silane to 210 GPa at 300 K: optical evidence of an insulator-semiconductor transition.
Silane (SiH(4)) has been studied in a diamond anvil cell from 7-210 GPa by using optical reflection and absorption techniques at 300 K. The reflectivity and transmission measurements showed a dramatic change in the neighbourhood of 100 GPa. On the basis of reflectivity and absorption experimental data, the pressure dependence of the refractive index (n) of solid SiH(4) was derived, which was th...
