Abstract

The cross-channel isospin amplitude {divides}M₀^{1 2}{divides} is measured in the single reaction γn → ρ{variant}⁰(pπ^-) at 7.5 GeV assuming the ρ{variant}⁰ dominance model. A low-mass enhancement is found for {divides}M₀^{1 2}{divides}² in the range of m(pπ^-) of ∼1.2 to ∼1.7 GeV. The reaction strongly violates s-channel helicity conservation but is consistent with t-channel helicity conservation. The {divides}M₀^{1 2}{divides} features are found to be very similar to those obtained in previous analyses of πp → π(Nπ) reactions.
