Spin observables for pion photoproduction on the deuteron in the Δ(1232)-resonance region
Abstract
Spin observables for the three charge states of the pion for the pion photoproduction reaction on the deuteron, γd → πNN, with polarized photon beam and/or oriented deuteron target are predicted. For the beam-target double-spin asymmetries, it is found that only the longitudinal asymmetries Tell20 and Tell2±2 do not vanish, whereas all the circular and the other longitudinal asymmetries do vanish. The sensitivity of spin observables to the model deuteron wavefunction is investigated. It has been found that only T21 and T22 are sensitive to the model deuteron wavefunction, in particular in the case of π0-production above the Δ-region, and that other asymmetries are not.
