Two small peaks at M ≈ 1004 MeV and 1044 MeV in the quasi-free reaction, are introduced in order to improve the fit. They would correspond to E$_{exc.}$=60 MeV and 80 MeV, if attributed to $^{12}$B. In Fig. 12, the oscillations are less pronounced than those in Fig. 11. At T$_{p}$ =2 GeV θ = 4 . 3 ◦ , - not illustrated - indications of small structures exist at masses close to M ≈ 1004 MeV and 1044 MeV. FIG. 12: (Color online.) Spectra of the $^{12}$C(d,2p)X reaction at T$_{p}$ =2 GeV θ = 0 ◦ [22]. (No vertical scale in the original paper). The cross-section of the p( $^{3}$He,t)Δ++ reaction was measured at many incident energies, and spectrometer angles, mostly at the SPES4 spectrometer at Saturne, but also at other places. The data from Dubna [23], at T$_{p}$=2.39 GeV, 4.53 GeV, and 8.33 GeV are not enough precise since their binning was taken as ΔE=25 MeV. They are not reanalyzed here. The $^{3}$He(p,t)Δ++ reaction was studied at SPES1 (Saturne) at forward angle in the laboratory system, with the motivation to reduce the contribution of the direct graph and study the possible (Δ $^{++}$,2n) component of the $^{3}$He wave function [24]. The beam energy was T$_{p}$=850 MeV. These data were taken at θ$_{lab.}$ = 6 ◦ , 10 ◦ , and 15 ◦ ; their cross-sections decrease fast with increasing angle, therefore only the cross-section of the smaller angle is shown here, in Fig. 13. We observe that indeed oscillations can be seen and are well fitted by the narrow struc- tures (see Table 2) if the data are shifted by ΔM=-9 MeV. This systematic shift may cor- respond to a possible saturation of the spectrometer magnetic field B, as small as δ p/p=6 10 − $^{3}$, possibly not taken into account for large triton momenta for the SPES1 spectrometer: p$_{t}$ ≈ 1.85 GeV/c. The shift may be due also to a bad knowledge of the incident beam energy, since for M$_{X}$=1250 MeV, ∂M$_{X}$ /∂T$_{p}$ =1.24 or to a bad knowledge of the spectrometer angle, since here ∂M$_{X}$ /∂θ$_{t}$ =-223.6 MeV/radian.
