Description

The cross-channel isospin amplitude modM0sup(1/2) is measured in the single reaction γn→rho0(pπ-) at 7.5 GeV assuming the rho0 dominance model. A low-mass enhancement is found for [modM0sup(1/2)]2 in the range of m(pπ-) of approximately 1.2 to approximately 1.7 GeV. The reaction strongly violates s-channel helicity conservation but is consistent with t-channel helicity conservation. The modM0sup(1/2) features are found to be very similar to those obtained in previous analyses of πp→π(Nπ) reactions. (Auth.)
