Multichannel Formalism for Positron-Hydrogen Scattering and Annihilation
A problem to account for the direct electron-positron annihilation in positron-hydrogen scattering above the positronium formation threshold has been resolved within the time independent formalism. The generalization of the optical theorem is derived for the case when an absorption potential is present in the Hamiltonian. With this theorem the annihilation cross section is fully determined by s...
متن کاملAnnihilation contributions in a Wilson-loop formalism.
The neglected annihilation contributions in the Wilson loop formalism of Eichten and Feinberg are defined and calculated. An annihilation time scale is introduced to discriminate the glueball contributions from true annihilation contributions to isoscalar-pseudoscalar meson states. In this formalism, it is found that there is no mixing between two quarkonium states with different quark masses t...
متن کاملSemiempirical model of positron scattering and annihilation
A two-parameter semiempirical theory of positron scattering and annihilation is developed and used to investigate the behavior of positrons interacting with the rare gases and metal vapors. The two-parameter theory is able to do a reasonable job of reproducing existing cross section and annihilation data for the rare gases. A model-potential calculation that correctly predicts the behavior of t...
متن کاملOutline of Neutron Scattering Formalism
Neutron scattering formalism is briefly surveyed. Topics touched upon include coherent and incoherent scattering, bound and free cross-sections, the Van Hove formalism, magnetic scattering, elastic scattering, the static approximation, sum rules, small angle scattering, inelastic scattering, thermal diffuse scattering, quasielastic scattering, and neutron optics.
متن کاملMultiple scattering theory for non-local and multichannel potentials.
Methodological advances in multiple scattering theory (MST) in both wave and Green's function versions are reported for the calculation of electronic ground and excited state properties of condensed matter systems with an emphasis on core-level photoemission and absorption spectra. Full-potential MST is reviewed and extended to non-local potentials. Multichannel MST is reformulated in terms of ...
