“…Where NC is corresponding few-nucleon correlation ( 3 He, 3 H, 2 H, and 4 He). According to kinematic calculations, a peak at the transferred energy ω 1 = 18.4 MeV to nucleus under investigation corresponds likely to quasi-elastic scattering 12 C(p, p ′ 8 Be) 4 He on a 8 Be -like nucleon cluster inside the carbon nucleus.…”

“…A high-momentum region, that begins close to the end of the IV range (Figs. 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.…”

“…7. According to kinematic calculations, a rather narrow peak at K = 1658 MeV/c (at the ω 1 = 14.9 MeV) corresponds likely to quasielastic scattering 12 C(p, p ′ 8 Be) 4 He on a 8 Be -like nucleon cluster inside the carbon nucleus. A value of the measured polarization of the secondary protons in the quasi-elastic scattering on this cluster is given in Fig.…”

“…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].…”

Available data on the polarization of the secondary proton (as a function of its momentum K) in the inelastic (p, p ′ ) reactions with the 9 Be, 12 C, and 40 Ca nuclei and differential cross section data (the momentum distributions) for the reactions at the initial proton energy 1 GeV and scattering angles Θ=21 • and Θ=24.5 • were analysed in a range of the high momenta K close to the momentum corresponding to the proton elastic scattering off the investigated nucleus. A structure in the polarization and momentum distribution data at the high momenum K, related probably to quasi-elastic scattering off a 8 Be-like nucleon cluster inside the nuclei, was observed.
