Proton-Proton Scattering at 340 Mev

Proton-Deuteron Elastic Scattering from 2.5 to 22.5 MeV

We present the results of a calculation of differential cross sections and polarization observables for proton-deuteron elastic scattering, for proton laboratory energies from 2.5 to 22.5 MeV. The Paris potential parametrisation of the nuclear force is used. As solution method for the charged-composite particle equations the ’screening and renormalisation approach’ is adopted which allows to co...

Duality and Proton - Proton Scattering at All Angles

: \ We obtain a very good description of all available large angle pp elastic scattering data using a dual model with logarithmic trajectories. Our fit strongly suggests that the dual amplitude is responsible for filling in ,a pronounced dip produced by the Pomeranchuk singularity. This new explanation of the shoulder in pp data survives the test of an enormous extrapolation from s N, 26-(GeV/~...

SLAC -PUB-238 December 1966 THE ABSOLUTE VALUE OF Axx (90’) FOR PROTON-PROTON SCATTERING AT 11.4 MeV

Because of the deterioration of the target under proton bombardment, Catillon, Chapellier, and Garreta normalize their measurements of Axx(900) and Ayy(900) at 11,4, 19.15, 23.45, and 26.5 MeV to the value of Axx(900) at 11.4 MeV. In order to provide an absolute normalization for these experiments we note that at 90° the value of A, is related to the ratio A Y-d Axx by the equation l+Axx = (l-A...

Bounds in proton-proton elastic scattering at low momentum transfer

We present a bound on the imaginary part of the single helicity-flip amplitude for spin 1/2-spin 1/2 scattering at small momentum transfer. The variational method of Lagrange multipliers is employed to optimize the single-flip amplitude using the values of σtot, σel and diffraction slope as equality constraints in addition to the inequality constraints resulting from unitarity. Such bounds prov...
