Contribution of A-resonance mechanism to elastic backward pd-scattering over T o = 0.5-0.8 GeV range of incident energy is analyzed. As distinct from [1-3], the parameters of NN~NA amplitudes in the phenomenology of one-meson 7c-and p-exchange are determined from pp~pn~ + reaction immediately in the kinematic region where the process pd~dp occurs. It has been found as a result that in the vicinity of the region where A-isobar is present on-mass-shell, the coherent sum of the amplitudes of A-resonance mechanism, relativistic one-nucleon exchange and single scattering predicts the pd ~ dp cross-section to be twice smaller than the experimental one and does not describe the tensor polarization of t2o deuteron. Possible causes of this discrepancy as well as the relation between the mechanisms of pd~dp process and the data on reactions of quasi-elastic knock-out of fast deuterons by protons (p, pd) from light nuclei, are discussed.

The deuteron breakup reaction pd → {pp} s n, where {pp} s is a fast proton pair emitted in forward direction with small excitation energy E pp < 3 MeV, has been studied at proton beam energies of 0.5-2.0 GeV using the ANKE spectrometer at COSY-Jülich. The differential c.m. cross sections are measured in complete kinematics and provide angular distributions of the neutron emission angle in the range θ n = 168 •-180 • , the dependence on beam energy at θ n = 180 • , angular distributions of the direction of the proton in the pp rest frame, and distributions of the excitation energy E pp of the proton pair. The obtained data are analyzed on the basis of theoretical models previously developed for the pd → dp process in a similar kinematics and properly modified for the diproton channel in pd → {pp} s n. It is shown that the measured observables are highly sensitive to the short-range part of the nucleon-nucleon interaction.

The series of calculations of differential cross sections and analyzing powers (АB у B ) of the elastic proton scattering on isotopes P 6 PHe and P 8 PHe was presented in the framework of the theory of Glauber multiple diffraction scattering. The three-body α−n−n and harmonic oscillator wave functions were used for P 6 PHe, for P 8 PHe -the function of density distribution in LSSM. For рP 6 PНе scattering the expansion of the Glauber operator into a series of multiple scattering is written in the form consistent with the picture of weakly bound clusters in halo-nuclei, for рP 8 PНе scattering the members of single-and double collisions are included in the operator. We have done the comparison of our results with available experimental data (including new data of АB у B for рP 6 PНе scattering at the E = 71 MeV/nucleon) and with the calculations results in the other approaches (high-energy, optical model, RMF). Also, the comparison of the characteristics of two isotopes P 6 PНе and P 8 PНе was made, which showed that they correlate quite well with each other.

Within the framework of the Glauber diffraction theory, the differential cross sections of the elastic р 6 Не, p 8 Li, and p 9 Li scattering were calculated at intermediate energies from 70 to 1000 MeV/nucleon. The use of realistic three-body wave functions −n−n ( 6 He), −t−n ( 8 Li), and −t−2n ( 9 Li), obtained in the framework of modern nuclear models, and the expansion of the Glauber operator into a series of multiple scatterings in a form that is well adapted to the three-body nuclei configuration, allows the calculation of the matrix elements, by taking into account the rescattering from all structure components of the designated nuclei.
