Application of the Non-Orthogonal Laguerre-L2 Basis to the Calculation of Electron-Helium Scattering at Intermediate Energy (Penggunaan Asas Tak Ortogon Laguerre-L2 untuk Pengiraan Serakan Elektron-Helium pada Tenaga Pertengahan)

چکیده
Differential cross sections for excitation to the n=2 states of atomic helium by electrons were computed for incident energies in the range from 30 to 50 eV. The n=2 states excitation cross sections are calculated with the use of closecoupling expansion with a non-orthogonal Laguerre-L2 basis function. The present status of agreement between theory and experiment for excitation of the ground-state was quite satisfactory.

The Application of the Pseudostate-Close-Coupling Method Using a Non-Orthogonal Laguerre-L Basis for Electron-Helium Scattering
Differential and total cross sections for elastic and excitation from the ground state to n ≤ 2 states of atomic helium by electrons are computed for incident energies in the range from 5 to 50 eV. The states excitation cross sections are calculated with the use of close-coupling expansion with a non-orthogonal Laguerre-L basis function. Our method is a frozen-core model of the target in which ...
متن کاملElectron-impact ionization of helium for equal-energy-sharing kinematics
The close-coupling approach to electron-helium single ionization is analyzed and several ways of defining the scattering amplitudes are determined, for both equaland unequal-energy outgoing electrons. Nevertheless, the various definitions all lead to the same cross section. The convergent close-coupling sCCCd method with Laguerre sCCC-Ld and box-based sCCC-Bd target functions is applied to calc...
متن کاملBox-based and Laguerre-based convergent close-coupling calculations of electron–helium ionization
We apply a new implementation of the convergent close-coupling (CCC) method to electron–helium scattering. The target states are obtained from one-electron He+ box-based eigenstates rather than the usual Laguerre-based orbitals. The utility of the new method is demonstrated for 50 eV electronimpact ionization of helium with three different energy sharings between the two outgoing electrons. Exc...
متن کاملExtended Jacobi and Laguerre Functions and their Applications
The aim of this paper is to introduce two new extensions of the Jacobi and Laguerre polynomials as the eigenfunctions of two non-classical Sturm-Liouville problems. We prove some important properties of these operators such as: These sets of functions are orthogonal with respect to a positive de nite inner product de ned over the compact intervals [-1, 1] and [0,1), respectively and also th...
متن کاملA Generalization of the Prolate Spheroidal Wave Functions
Many systems of orthogonal polynomials and functions are bases of a variety of function spaces, such as the Hermite and Laguerre functions which are orthogonal bases of L2(−∞,∞) and L2(0,∞), and the Jacobi polynomials which are an orthogonal basis of a weighted L2(−1, 1). The associated Legendre functions, and more generally, the spheroidal wave functions are also an orthogonal basis of L2(−1, ...
