Abstract
We investigate the photoproduction in the reaction within the effective Lagrangian method near threshold. In addition to the "background" contributions from the contact, channel exchange, and channel nucleon pole terms, which were already considered in previous works, the contribution from the nucleon resonance (spin-parity ) is also considered. We show that the inclusion of the nucleon resonance leads to a fairly good description of the new LEPS differential cross-section data, and that these measurements can be used to determine some of the properties of this latter resonance.
