Single and double delta production in the He-3(gamma,pi(+)pi(-)) reaction at 380<=E-gamma<=700 MeV

Results are presented for the He-3(gamma, pi(+)pi(-)) reaction in the region 380 less than or equal to E-gamma less than or equal to 700 MeV, investigated with the use of a 10% duly factor tagged photon beam, in conjunction with the TAGX multiparticle spectrometer. The study of such multipion photoproduction reactions has motivated a number of chiral symmetric models, and is expected to provide an insight on the role of the Delta and N* resonances in the nuclear medium. From comparisons of the data with simple reaction simulations, it was found that the data were best Bt with a combination of multibody phase space channels, quasifree Delta and N*, and Delta Delta production channels. The results are compared with other double pion photoproduction reactions on hydrogen and deuterium.
