“…For angles below 50', the 2 values obtained in this experiment are in excellent agreement with those obtained by Barlett et al. [3] and Bystricky et al [4], and generally power results of the present experiment at 797 MeV with those of Ba-83 (Barlett et al [3]) and By-85 (Bystricky et al [4]) at 800 MeV, and with "free" n-p analyzing power results from Gl-90 (Glass et al [5]), ¹89(Newsom et al [6]), and (Korolev et ai.

“…The fit of Bugg [21] apparently is influenced much more by the data of Korolev et ah. Apparently, the data of Newsom et a/. were not included in the database for the Saclay fit [22] and its large-angle behavior is strongly influenced by the larger-angle data of Barlett et al [3]. It deviates considerably from the results of this experiment and those obtained by Newsom et al In part, the differences in 4.…”

Forward angle analyzing power inp→-nandp→-pquasifree scattering at 643 and 797 MeV

Polarized proton beams and a liquid-deuterium target were used to measure the analyzing power for quasifree p-n and p-p scattering in the forward direction at 643 and 797 MeV. Alternate use of a liquidhydrogen target provided a comparison of free and quasifree p-p scattering. The precision of the data is in general +0.01 to +0.02, although some of the p-p data for 797 MeV are at the precision level of +0.005. For c.m. angles 0*~22' there is no difference between quasifree and free results at either energy. The data are compared with the predictions of several phase-shift analyses. In a search for more pronounced quasifree scattering effects, a small amount of p-"p" data were taken with a carbon target.

“…The trend of the new data in the resonance region deviates clearly from that exhibited by the data from previous experiments below and above this region [8][9][10][22][23][24][25][26][27]. The new partial-wave solutions (see below) connect all data within their uncertainties, whereas the SP07 solution obviously fails in the resonance region.…”

New data on quasifree polarized neutron-proton scattering, in the region of the recently observed d * resonance structure, have been obtained by exclusive and kinematically complete high-statistics measurements with WASA at COSY. This paper details the determination of the beam polarization, 2 checks of the quasifree character of the scattering process, on all obtained Ay angular distributions and on the new partial-wave analysis, which includes the new data producing a resonance pole in the 3 D3-3 G3 coupled partial waves at (2380±10−i40±5) MeV -in accordance with the d * dibaryon resonance hypothesis. The effect of the new partial-wave solution on the description of total and differential cross section data as well as specific combinations of spin-correlation and spin-transfer observables available from COSY-ANKE measurements at T d = 2.27 GeV is discussed.

“…In addition, the spindependent total cross sections b, ol and b.oT [14 -17] have recently been measured. Finally, the analyzing power [6] Atv and spin-depolarization parameters D;1 have been measured for the quasifree reaction from the neutron in deuterium [18]. (Note that the quoted uncertainties for A& in Ref.…”

We have measured the spin-transfer parameters K«, KsL, KLs, and Kss at 788 MeV from 47 to 177' c.m. , and also uncovered a 10 -16 /o normalization discrepancy which affects all previous np elastic spin data from LAMPF. Results disagree significantly from previous phase-shift predictions. With the inclusion of these new data the NN phase shifts and amplitudes (isospin 0 and 1) become well determined for the first time near 800 MeV.
