Quasi-elastic scattering of proton with 1 GeV energy on eight-nucleon cluster inside nucleus

“…3, 4) corresponds mainly to quasi-elastic scattering on the residual nuclei X from the reactions 9 Be(p, p ′ NC)X noted above: 9 Be(p, p ′ 6 Li) 3 H, 9 Be(p, p ′ 6 He) 3 He, 9 Be(p, p ′ 7 Li) 2 H, and 9 Be(p, p ′ 5 He) 4 He. This overlap of the momentum intervals for the reaction 9 Be(p, p ′ 4 He) 5 He (interval IV) and, mainly, for the reactions 9 Be(p, p ′ 6 Li) 3 H and 9 Be(p, p ′ 6 He) 3 He with the light nucleus, 9 Be, is due to relatively close masses of the correlations and residual nuclei.…”

“…The momentum interval VIII (IV) corresponds to quasi-elastic scattering on a 8 Be -like (a 4 He -like) nucleon cluster. 9 Be(p, p ′ 4 He) 5 He for the interval IV. A high-momentum region, that begins close to the end of the IV range (Figs.…”

“…This work is a part of the experimental program in the framework of which the effects of nucleon clusterization in nuclear matter is studied in the inclusive (p, p ′ ) experiments at the PNPI synchrocyclotron with the 1 GeV proton beam [1,2,3,4,5,6,7].…”

“…Earlier, the secondary proton polarization (P ) and its momentum distribution (differential cross section σ incl = d 2 σ dΩdK ) in the inelastic (p, p ′ ) reaction with nucleus were measured at the scattered angle of Θ=21 [4], 40 Ca [3], 56 Fe [4], and 90 Zr [5] were investigated. The structure in these experimental data was observed that possibly related to quasi-elastic scattering in the momentum intervals II, III, and IV on two-nucleon ( 2 H), three-nucleon ( 3 He, 3 H), and four-nucleon ( 4 He) correlations, respectively [9,10].…”
