Elastic differential cross sections and analyzing powers for p+40,42,44,48Ca at 0.8 GeV☆

Abstract Differential cross sections and analyzing powers for the elastic scattering of 800 MeV polarized protons from 40,42,44,48Ca are reported. A first-order, spin-dependent KMT optical potential analysis is presented from which the rms radii of the neutron densities are deduced. A comparison of these results with other determinations and with various theoretical predictions is given.

Elastic differential cross sections and analyzing powers for p + 54Fe, 58,64Ni at 800 MeV

Abstract Elastic scattering analyzing powers and differential cross sections for 800 MeV → p + 54Fe, 58,64Ni are reported. An approximately mode-independent technique is used to extract information concerning the neutron density distributions of these nuclei.

“Backward” production of protons, deuterons, tritons, 3He, 4He and pions in the interaction of 400 GeV protons with nuclei

Results of measurements of inclusive cross sections, p(400 GeV) + (6Li, Ta) → (p, d, t, 3He, 4He, π±) + Xat 90° and 160° (lab) for detected particles in the momentum range 0.1 to 1.4 Gev/c are reported. The A dependence of these cross sections is also presented for 6Li, Be, C, Al, Cu, and Ta, at a momentum of 0.7 GeV/c. This cross section dependence increases faster than A, at different rates for observed π+, p, d, and t, and considerably more steeply than such cross sections at low incident energies (near 1 GeV).

Elastic pp scattering at 1.463 GeV/c in the Coulomb interference region☆

Abstract The differential cross section for elastic pp scattering has been measured at 800 MeV, for laboratory angles ranging between 1.2° and 4.3° (lab). The ratio ϱ of the real to imaginary parts of the forward spin-independent scattering amplitude and the combined magnitudes of the forward double spin-flip amplitudes have been extracted from the data and are compared with the results of recent forward dispersion relation calculations and phase shift analyses.
