Spin correlation parameter Axx and Ayy measurements in p-p scattering from 11 MeV to 26 MeV

Phase shift analysis of 0–30 MeV pp scattering data

“…To make such a representation of the χ 2 hypersurface, we divided the data into clusters around 0.38254 MeV (the interference minimum), 1 MeV, 5 MeV, 10 MeV and 25 MeV. We had to split one group [95], because it contained data from 11 to 26 MeV. From these clusters we determined the single-energy phases and inverse error matrices of Table IX in the same way as we determined single-group phases for groups with data points at different energies (Sec.…”

Phase-Shift Analysis of High-Precision (p, p) Polarization Data at 19.7 MeV

“…These measurements are of interest for two reasons: (1) They, together with recent 2 and forthcoming experiments from Saclay, constitute the first of a new generation of very precise low-energy nucleon-nucleon measurements which feature the use of polarized beams and/ or polarized targets. (2) The new Berkeley data are in flat contradiction with other types of iP,P) data at neighboring energies.…”

S-Wave Shape-Dependent Scattering Parameters of the Proton-Proton Interaction

“…Noyes and Lipinski 11 have recently reanalyzed the data at 9.69 MeV extrapolating the recent information on spincorrelation parameters. 12 They conclude that at 9.69 MeV there is modest evidence for shape dependence consistent with one-pion exchange (OPE). However, the cross section measured at 9.69 MeV may be systematically high as noted by several authors, 11 ' 13 ?…”
