Abstract
We demonstrate a concise method to enumerate the number of generalized pola rizabilities-quantities characterizing the independent observables in singl y virtual Compton scattering-for a target particle of arbitrary spin s. By using crossing symmetry and J(PC) conservation. we show that this number is (10s + 1 + delta (s,0)).
