The H-2(gamma,pp pi(-)) reaction cross section has been measured in the energy range 220 MeV less than or equal to E(gamma)less than or equal to 280 MeV at the Saskatchewan Accelerator Laboratory using the Saskatchewan-Alberta Large Acceptance Detector. This is the first reported measurement of the gamma(2)H-->pp pi(-) cross section covering a wide range of phase space in an attempt to study final state interactions. The cross section for this reaction is compared to the calculation of Blomqvist and Laget with various contributions from final state interactions. Blomqvist and Laget's theory is successful in describing the shapes of the distributions, as well as the overall magnitude of the cross section. The different final state interactions have an overall effect of 10%-15% on the single differential cross section, with the calculation that includes the Delta-N interaction having the best agreement with the data.

The Saskatchewan-Alberta Large Acceptance Detector (SALAD) is a 4π detector designed and built for studies of photonuclear reactions with a tagged photon beam. The design and performance of the detector are described. Its characteristics have been studied by examining p-p elastic scattering with a proton beam at TRIUMF.
