ON COMPLETE-SETS OF POLARIZATION OBSERVABLES

A new criterion is developed which provides a check as to whether a ch osen set of polarization observables is complete with respect to the d etermination of all independent T-matrix elements of a reaction of the type a + b --> c + d +... As an illustrative example, this criterion is applied to the longitudinal observables of deuteron electrodisinteg ration. (C) 1998 Elsevier Science B. V.
