I use pseudospectral methods defined with a set of Hermite polynomials and with a set of half-range, nonclassical Hermite polynomials to test their applicability in analyzing the motion of a particle in symmetric double-well harmonic potentials. The

The relaxation of a nonequilibrium distribution of electrons in a mixture of SF6 and Ar is studied. In this paper, electron-SF6 and electron-inert gas elastic collisions, vibrationally inelastic collisions between electrons and SF6, as well as the el

The relaxation of a nonequilibrium distribution of electrons in a mixture of CCl4 with either Ar or Ne is studied. In this paper, electron-CCl4 and electron-inert gas elastic collisions, vibrationally inelastic collisions between electrons and CCl4,

The relaxation of a nonequilibrium distribution of electrons in a mixture of Ar and CCl 4 is studied. In a previous paper [J. Phys. B 34 (1991) 2909], Shizgal demonstrated that with the neglect of vibrationally inelastic collisions, a nonequilibrium

The time-dependent Boltzmann equation is applied to the study of the degradation and thermalization of a nonequilibrium distribution of subexcitation electrons in SiH 4 . For the small electron to SiH 4 mass ratio, the collision operators in the Bolt

The relaxation to equilibrium of an ensemble of electrons dilutely dispersed in a large excess of CH4 is studied with solutions of the Boltzmann equation. Elastic and vibrationally inelastic collision processes are included in the analysis. The relax

The Spencer—Fano equation (SFE) is often used to study the energy distribution of energetic electrons and their moderation in gases. Although accurate results can be obtained from a numerical solution of the SFE, the calculations are time-consuming

The thermalization of electrons in gaseous moderators for initial nonequilibrium distributions not far removed from thermal energies has been studied previously with a Fokker—Planck equation for electron distribution. For electron energies in the k

Time-dependent electron degradation spectra and yields of initial products are studied for the Ar-H{sub 2} mixture by using the time-dependent Spencer-Fano (TDSF) theory. An integral form of the TDSF equation is derived and applied in numerical solut

We point out a relation between the electron degradation spectra determined by two differing cross-section sets but subject to the same source. The relation takes a form of the Fredholm integral equation of the second kind and may be viewed as an alt
