Complete sets of polarization observables in electromagnetic deuteron breakup

For deuteron photo- and electrodisintegration the selection of complete sets of polarization observables is discussed in detail by applying a recently developed new criterion for the check of completeness of a chosen set of observables. The question of ambiguities and their resolution by considering additional observables is discussed for a numerical example, for which the role of experimental uncertainties is also investigated. Furthermore, by inversion of the expressions of the observables as Hermitean forms in the t-matrix elements a bilinear term of the form t(j')*t(j) can be given as a complex linear form in the observables from which an explicit solution for t(j) in terms of observables can be obtained. These can also be used to select sets of observables for the explicit representation of the t-matrix.
