A large multi-cell threshold gas Cherenkov counter
A large multi-cell threshold gas Cherenkov counter consisting of 78 cells has been built for use in a high energy muon scattering experiment at CERN (European muon collaboration). It is used with neon, nitrogen or a mixture of these two gases, allowing the pion threshold to be varied between 6 and 20 GeV/c. The sensitive region of the counter has a length of 4.0 m and entrance and exit windows of 1.1*2.4 m/sup 2/ and 2.4*5.0 m/sup 2/, respectively. (8 refs)
Antiproton-proton annihilation into and at 6.2 GeV/c
The angular distribution for the two annihilation channels pp to pi /sup +/ pi /sup -/ and pp to K/sup +/K/sup -/ have been measured at 6.2 GeV/c. The two-pion channel shows peripheral peaks for pi /sup +/ and pi /sup -/ going forward, and the two-kaon channel shows a peripheral peak for the K/sup -/ going forward. The results have been compared with the line-reversed elastic backward scattering reactions and also with a constituent interchange model. (20 refs)
and elastic scattering at 6.2 GeV/c
Data on 6.2 GeV/c pi /sup -/p and K/sup -/p elastic scattering cross sections are presented in the range 0.3<-t<10.7 (GeV/c)/sup 2/. Large- angle pi /sup -/p scattering differential cross sections oscillate around an average differential cross section of 50 nb/(GeV/c)/sup 2/, with minima at cos theta /sub cm/ approximately=0 and -0.4. The well- known dip at -t=2.8 (GeV/c)/sup 2/ remains constant in t. In the backward direction there is a dip at -u approximately=1 (GeV/c)/sup 2 /. K/sup -/p elastic scattering has a diffraction peak with a slope of 7.30+or-0.08 (GeV/c)/sup -2/ in the region 0.3<-t<0.6 (GeV/c)/sup 2/. The structure at about -t=1 (GeV/c)/sup 2/ is less pronounced than at 5 GeV/c. The large-angle region is characterized by a very fast decrease of the differential cross section with increasing energy. (67 refs)
