摘要: Abstract It is shown that there a discrepancy in the isovector photoproduction amplitude between predictions of dispersion relations and experimental data. This cannot be removed by introduction an isotensor electromagnetic current. For considered isotopic combination result practically does not depend on possible ambiguities solution relations.
