We have measured the analyzing power in π+, π−, and KS0 production by a polarized proton beam at 13.3 and 18.5 GeV/c. The data cover the central and the beam fragmentation region, in the transverse-momentum range up to 2 GeV/c. The results indicate that sizable effects are present at high xF and also persist into the hard-scattering region for KS0 and π+. A zero value of the analyzing power was observed for π− production.

CHARGED PIONS FROM THE ISOTOPES NI-58, NI-64 BY 201-MEV PROTONS

Palmeri, A. ; Aiello, S. ; Badala, A. ; et al.

Phys.Rev.C 40 (1989) 1081-1084, 1989.

Charged pion production induced by 201 MeV protons on Ni58 and Ni64 has been studied. The double differential cross sections have been measured over a wide angular range. Different behavior of the angular distribution is observed for low and high energy pions. The yield of positive pions shows a pronounced forward peaked component. The deduced total production yields are about the same for (p,π+) on both isotopes whereas that for (p64,π−) is twice as large as for (p58,π−).

High yields of low-momentum pions were obtained from high-energy primary proton beams. The results are discussed, also with respect to the possibility of setting up cloud muon beams from the very lowmomentum poins produced by 10 GeV/c protons.
