Compton scattering from positronium and validity of the impulse approximation
Abstract
The cross sections for Compton scattering from positronium are calculated in the range from 1 to 100 keV incident photon energy. The calculations are based on the A{sup 2} term of the photonelectron or photonpositron interaction. Unlike in hydrogen, the scattering occurs from two centers and the interference effect plays an important role for energies below 8 keV. Because of the interference, the criterion for validity of the impulse approximation for positronium is more restrictive compared to that for hydrogen.

Validity of the relativistic impulse approximation for elastic protonnucleus scattering at energies lower than 200 MeV
We present the first study to examine the validity of the relativistic impulse approximation (RIA) for describing elastic protonnucleus scattering at incident laboratory kinetic energies lower than 200 MeV. For simplicity we choose a {sup 208}Pb target, which is a spinsaturated spherical nucleus for which reliable nuclear structure models exist. Microscopic scalar and vector optical potentials are generated by folding invariant scalar and vector scattering nucleonnucleon (NN) amplitudes, based on our recently developed relativistic mesonexchange model, with Lorentz scalar and vector densities resulting from the accurately calibrated PK1 relativistic mean field model of nuclear structure. It is seen that phenomenologicalmore » 
Comptonscattering studies on the helium atom beyond the impulse approximation
A series expansion of the Born propagator allows one to represent successive corrections to the impulse approximation and exhibits their relative dependence in momentum transfer k and the Compton (targetstructure) parameter q. The proposed treatment provides a physical interpretation of the observed Compton defects. It is shown here to be in close agreement with highenergyelectronimpact spectroscopy measurements obtained for helium atoms. 
Lowmomentumtransfer nonrelativistic limit of the relativistic impulse approximation expression for Comptonscattering doubly differential cross sections and characterization of their relativistic contributions
The nonrelativistic (nr) impulse approximation (NRIA) expression for Comptonscattering doubly differential cross sections (DDCS) for inelastic photon scattering is recovered from the corresponding relativistic expression (RIA) of Ribberfors [Phys. Rev. B 12, 2067 (1975)] in the limit of low momentum transfer (q{yields}0), valid even at relativistic incident photon energies {omega}{sub 1}>m provided that the average initial momentum of the ejected electron <p{sub i}> is not too high, that is, <p{sub i}> <m. This corresponds to a binding energy E{sub b}<10 keV. This q{yields}0 nr limit is simultaneous with the approach of the scattering angle {theta} to 0 deg. ({theta}{yields}0 deg.)more » 
Multiple scattering effects in quasifree scattering from halo nuclei: A test of the distortedwave impulse approximation
Full Faddeevtype calculations are performed for {sup 11}Be breakup on a proton target at 38.4, 100, and 200 MeV/u incident energies. The convergence of the multiple scattering expansion is investigated. The results are compared with those of other frameworks like distortedwave impulse approximation that are based on an incomplete and truncated multiple scattering expansion.
