Matrix variational method
Abstract
A general formalism is described for the matrix variational method, applicable to multichannel electron scattering by a many-electron atom, for energies below the first ionization threshold. Physical interpretation of the method and its relationship to others (close-coupling and polarized orbital methods) are discussed. Recent computations by this method of elastic and inelastic electron scattering are reviewed. © 1974.
