Abstract The polarization transfer parameters,KNN and KLL, have been measured in p d→ n X and p 9Be→ n X at 0° and 800 MeV. The quasifree p d→ n X values for KNN and KLL are close to the free n-p measured values. The rather large values of KLL demonstrate that this transfer mechanism will provide a useful source of polarized neutrons at medium energies.

Abstract The spin-transfer parameters K NN and K LL have been measured for at 0° and 800 MeV for neutron momenta between 700 and 1200 MeV c . Peak values of K NN and K LL are −0.30 ± 0.05 and −0.5 ± 0.1 respectively. These results are in substantial disagreement with VerWests field theoretic model.

Abstract Measurements of the spin transfer parameters, KNN and KLL, at 500, 650 and 800 MeV are presented for the reaction p d → n pp at 0°. The data are useful input to the NN data base and indicate that the quasi-free charge exchange (CEX) reaction us a useful mechanism for producing neutrons with at least 40% polarization at energies as low as 500 MeV.

A device, dubbed QPAN, for determining the polarization of an intermediate energy neutron beam has been developed. QPAN consists of a double arm scintillator range telescope viewing a CH2 target. The effective analyzing power was measured to be 0.18 ± 0.01.

Measurements of A/sub L/L between 500 and 800 MeV and spin dependent cross sections derived from these measurements are presented for the reaction pp..--> pi..d at c.m. angles theta/sub ..pi../( of 50/sup 0/, 70/sup 0/, and 90/sup 0/. Angular distributions for A/sub S/L are also presented for energies 500, 650, and 800 MeV. These are the first measurements of spin-correlation parameters in this channel above 590 MeV, and are in substantial disagreement with theoretical predictions of the triplet amplitudes above 600 MeV.

The spin correlation parameter Ann for free n‐p scattering has been measured for 300–665 MeV over an angular range 70°–166° cm. This is the first Ann measurement in this energy region. The results are compared with predictions from the existing nucleon‐nucleon phase shift solutions.
