Abstract
We study the photoproduction of scalar mesons close to the threshold of f(0 )(980) and a(0)(980) using a unitary chiral model. Peaks for both resonance s show up in the invariant mass distributions of pairs of pseudoscalar meso ns. A discussion is made on the photoproduction of these resonances in nucl ei, which can shed light on their nature, a subject of continuous debate. [ S0556-2813(99)01507-1].
