We show that the measurement of the spin singlet and triplet cross sections for the reaction p→p→ → σ<sup>+</sup>θ<sup>+</sup> will unambiguously determine the parity of the θ<sup>+</sup>.enCopyright (c) 2004 Progress of Theoretical PhysicsA method to unambiguously determine the parity of the Θ⁺ pentaquarkA method to unambiguously determine the parity of the Theta(+) pentaquarkJournal article002004023710.1143/PTP.111.2910002201571000082-s2.0-214265579457196Thomas, A.
