Problems associated with the measurement of coherence parameters - Superelastic electron scattering by laser-excited Ba-138(...6s6p1P1) atoms
Abstract
Measurements of superelastic scattering of electrons by laser-excited Ba-138(...6s6p1P1) atoms were carried out. An asymmetry observed has been explained using a model of scattering from a target with finite dimensions. This model employed coherence parameters which were calculated in the distorted-wave approximation. The results indicated that the interpretation of coherence experiments in terms of scattering from a pointlike target can lead to serious errors in the deduction of coherence parameters at low scattering angles.
