• Descrição: We study two-body currents in the noninteracting relativistic Fermi gas model. Special emphasis is put on the role of the [Delta] isobar. Due to a resonance behavior, relativistic two-body isobar currents are found to be important in comparison with experimental data. Real-pion production is studied within the same framework, and the importance and physical implications of the energy dependence of the [Delta]-isobar decay width are stressed.
