Precision Measurement of n p Charge Exchange Cross-Section at 647-MeV

Evans, M.L. ; Glass, G. ; Hiebert, J.C. ; et al.

The differential cross section for n−p elastic scattering in the angular region 145°<θc.m.<180° has been measured with high statistical accuracy using the monoenergetic neutron beam at Clinton P. Anderson Meson Physics Facility. The results differ significantly from previous Dubna and Princeton-Pennsylvania Accelerator results but agree reasonably well with recent Saclay data except at extreme backward angles.

Measurements of the differential cross-section of the reaction p p ---> d pi+ from 3.0 to 5.0 gev/c

Anderson, H.L. ; Larson, D.A. ; Myrianthopoulos, L.C. ; et al.

A measurement of the complete differential cross section for the reaction pp→dπ+ at 3.00, 3.20, 3.43, 3.65, 3.83, 4.00, 4.20, and 5.05 GeVc incident proton momentum has been made in an attempt to establish the role of the Δ (1950) in this region. The data show that the previously observed enhancement in the forward cross section between 3 and 4 GeVc due to this isobar is an effect which damps out quickly as the production angle departs from zero degrees, in contrast with the well-known enhancement at 1.35 GeVc, which is evident at all angles. In particular, the one-pion-exchange model is in poor agreement with the extended set of data. A detailed description is given of a novel proportional-wire-chamber system which facilitated the selection of this rather rare reaction from a very high competing background.

Wide-angle proton-proton elastic scattering from 1.3 to 3.0 gev/c

Williams, D.T. ; Bloodworth, I.J. ; Eisenhandler, E. ; et al.
Nuovo Cim.A 8 (1972) 447-469, 1972.
Inspire Record 78276 DOI 10.17182/hepdata.37468

Differential cross-sections for proton-proton elastic scattering have been measured covering the angular range from 50° to 90° c.m. at twelve incident momenta from 1.3 to 3.0 GeV/c. The angular distributions are quite smooth, but there is evidence of structure in the energy dependence of fixed-angle cross-sections at |t| ∼ 1 (GeV)2.
