Abstract

The electromagnetic NΔ(1232)N-\Delta(1232) transition amplitudes are calculated using the point-form of relativistic quantum mechanics. The relativistic effects incorporated in the electromagnetic matrix elements give a good description of the transition amplitudes to the Δ(1232)\Delta(1232) resonance, reproducing well the Q2Q^2 behaviour of the data, apart from the low Q2Q^2 one.
