Abstract |
|
|
| The double polarization E-asymmetry for the −→g −→d → p0d reaction is predicted for incident photon lab-energies near
the h-threshold at backward center-of-mass emission pion angles. The influence of first-order rescattering effect with intermediate
production of both p- and h-mesons on the E-asymmetry is investigated. A strong effect from first-order rescattering is obtained. It
reached on average about 40% at extreme backward direction in the h-threshold region. In addition, the sensitivity of the results to the
elementary pion photoproduction operator and deuteron wave function is also investigated. Considerable dependence of the results on
the elementary amplitude and deuteron wave function is found. |
