摘要: The electromagnetic N−Δ(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) resonance, reproducing well the Q2 behaviour of the data, apart from the low Q2 one.
