FIG. 19: (Color online) Angular distributions of some narrow baryonic structures extracted from the d( $^{3}$He,t)X reaction. M=1044 MeV, full circle, black; M=1094 MeV, full square, red; M=1136 MeV, full triangle, green; M=1213 MeV, full star, blue; M=1247 MeV, empty circle, sky blue; M=1274 MeV, empty square, purple. Fig. 19 shows the angular distributions at forward angles of six narrow structures: M=1044 MeV, 1094 MeV, 1136 MeV, 1213 MeV, 1247 MeV, and 1274 MeV. The error bars are set arbitrarily to 10%. The cross-sections decrease continuously with increasing angle, more or less parallel to each other. These regular (non oscillating) shapes of the angular distributions, can be considered as an useful argument with respect to the present cross-section reanalysis. The $^{12}$C ( $^{3}$He,t) reaction was studied at Saturne (SPES4 beam line) [27–29] at T 3 $_{He}$=2 GeV, θ = 0 ◦ . Fig. 20 shows the result after adding the narrow structures to the theoretical analysis performed by [28]. FIG. 20: (Color online.) Cross-section of the $^{12}$C ( $^{3}$He,t) reaction at T 3 $_{He}$=2 GeV, θ = 0 $^{◦}$. [27] [28]. The text explains the content of the theoretical calculations performed by [28]. Insert (a) shows the double differential cross-section; insert (b) shows the pion coincidence spectrum. Insert (a) shows the double differential cross-section. The curve passing through the small empty circles is the final result of the calculation [28] within the isobar-hole model. It is obtained including the quasi-free Δ decay, the Δ spreading and the coherent pion production. Insert (b) shows the pion coincidence spectrum [29, 30]. The theoretical curves show the result of the calculations [28] performed with Landau-Migdal parameters: g ΔΔ = 0.33 (solid curve) and g ΔΔ = 0.4 (dashed curve). This last curve was renormalized by a factor of 1.5 by the authors. The narrow structures are extracted from the dashed curve. The extraction from the solid curve will change the amplitudes of these structures, but not their position. Here also we find the final fits show a remarkable agreement with the data. C.
