Polarization observables in dp backward elastic scattering at high and intermediate energies
The tensor analyzing power T20 and the polarization transfer coefficients κ0(= 3 2 K y ) and K xz are investigated for dp backward elastic scattering by the invariant-amplitude method. Discrepancies between the conventional calculations and the experimental data on T20 and κ0 at high and intermediate energies are mostly dissolved by including imaginary parts in the amplitudes. The quantity K xz...
متن کاملDifferential Cross Section of Dp-elastic Scattering at Intermediate Energies
The deuteron-proton elastic scattering is studied in the multiple scattering expansion formalism. The contributions of the one-nucleon-exchange, singleand double scattering are taken into account. The Love and Franey parameterization of the nucleon-nucleon t-matrix is used, that gives an opportunity to include the off-energy-shell effects into calculations. Differential cross sections are consi...
متن کاملRole of Intermediate Pions in pHe Backward Elastic Scattering
The mechanism of pHe backward elastic scattering is studied. It is found that the triangle diagrams with the subprocesses pd →Heπ and pd →Heπ, where d denotes a pn pair in the spin-singlet (S0) state, dominate in the cross section at 0.3-0.8 GeV, and their contribution is comparable with that for a sequential transfer of a np pair at 1-1.5 GeV. The contribution of the d, estimated on the basis ...
متن کاملStructure and Mechanisms of pHe Backward Elastic Scattering
The mechanism of pHe backward elastic scattering is studied. It is found that the triangle diagrams with the subprocesses pd →3Heπ0, pd →3Heπ0 and p(pp) →3Heπ+, where d and pp denote the singlet deuteron and diproton pair in the S0 state, respectively, dominate in the cross section at 0.3-0.8 GeV, and their contribution is comparable with that for a sequential transfer of a np pair at 1-1.5 GeV...
متن کاملMatrix theory of elastic wave scattering
Upon invoking Huygen's principle, matrix equations are obtained describing the scattering of waves by an obstacle of arbitrary shape immersed in an elastic medium. New relations are found connecting surface tractions with the divergence and curl of the displacement, and conservation laws are discussed. When mode conversion effects are arbitrarily suppressed by resetting appropriate matrix eleme...
