Nucleon-nucleon correlations in the reaction of photoelectric production of a Δ isobar on a tensor-polarized deuterium target

Abstract

Density matrix elements for a Δ isobar produced in the reaction γd→Δp are calculated in a relativistic momentum approximation. A correlation function is obtained for the directions of escape of the spectator proton and the nucleon from the decay Δ→Nπ. The influence of polarization of the target and of the potential of the nucleon-nucleon interaction on the correlation function is considered.
