It has been shown [S] that the combination of spin density matrix elements of p 11 +p I_ 1 describes a vector particle’s transverse polarization state perpendicular to the production plane, t Work supported by the US Atomic Energy Commis-sion. * On leave from Tel Aviv University, Tel Aviv, Israel.

N2 - Agreement with the Vector Dominance Model predictions are obtained in a system where the pion produced vector mesons are described in the Donohue-Högaasen frame. generalized to account for the presence of s-wave contributions. In this system the admixture of polarizations from the element ρ{variant}10V are suppressed by a dynamical unitary transformation on the helicity frame spin density matrix. The tests are applied to pion photoproduction data by polarized and unpolarized photons; also an independent search is made for the γ-ρ{variant} coupling constant at q2 = 0, yielding a value of γρ{variant}2/4π = 0.40 ± 0.03.
