Fig. 14 shows the cross-sections of the p( $^{3}$He,t)Δ++ reaction [25] measured at Saturne (SPES4 beam line) at T 3 $_{He}$=1.5 GeV, θ = 3 . 5 ◦ in insert (a), T 3 $_{He}$=2 GeV, θ = 5 ◦ in insert (b), and T 3 $_{He}$=2 GeV, θ = 0 ◦ in insert (c). The data are well fitted using the masses of narrow baryonic structures. Special attention has to be brought to the low mass spectra. Below M$_{X}$=1100 MeV, the data in Fig. 14 (empty squares) are rescaled by a factor of five. We observe here negative and positive numberq resulting from the subtraction of quite poor statistics data obtained with a CH 2 and a C targets. FIG. 13: (Color online.)
