摘要
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 resonances show up in the invariant mass distributions of pairs of pseudoscalar mesons. A discussion is made on the photoproduction of these resonances in nuclei, which can shed light on their nature, a subject of continuous debate. [S0556-2813(99)01507-1].
