We present data on the decay of the Δ resonance excited in 1H, 2H and 12C by the (3He, t) reaction at 2 GeV incident energy. In the energy transfer spectra, the same position and width of the Δ resonance are observed on the three targets when π+ and one proton are detected in coincidence with the triton.
On the 12C target, the Δ peak associated with the detection of two protons is shifted by 100 MeV towards lower excitation energy.
