Abstract

We present an analysis of a Beam-Target double polarization asymmetry in γn→ Θ⁺ K^-. We show that this quantity can serve as a filter for the determination of the Θ⁺'s spin-parity assignment near threshold. It is highly selective between 1/2⁺ and 1/2^- configurations due to dynamical reasons.
