The influence of the structure of a nucleus on the nuclear (3,3) resonance is discussed in the framework of a special kind of a particle hole model where the elementary excitation mode is assumed to be the transition of a bound nucleon into a (bound) Δ. The residual interaction between a nucleon and a Δ leads to a mixing of different particle-hole excitations and hence, collective effects are expected to show up, resulting for example in a shift of the main peak of the excitation spectrum; furthermore — due to quenching — a fine structure in the spectrum could be visible, — Recent experimental data on the ⁴He(γ,pπ^-) reaction can possibly be interpreted in the present model with an attractive NΔ residual interaction.
