Polarization observables in dp backward elastic scattering at high and intermediate energies
نویسنده
چکیده
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 is shown to be useful in criticizing nuclear force assumptions. PACS: 21.30.-x, 21.45.+v, 24.70.+s, 25.10.+s

Optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. Invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. Transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 GeVIC

متن کاملProton−deuteron elastic scattering above the deuteron breakup
The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by taking into account the long–range effect of the Coulomb interaction and using a realistic...
متن کاملReaction mechanism and characteristics of T 20 in d + 3 He backward elastic scattering at intermediate energies
For backward elastic scattering of deuterons by 3He, cross sections σ and tensor analyzing power T20 are measured at Ed = 140 − 270 MeV. The data are analyzed by the PWIA and by the general formula which includes virtual excitations of other channels, with the assumption of the proton transfer from 3He to the deuteron. Using 3He wave functions calculated by the Faddeev equation, the PWIA descri...
