Absolute differential cross sections for pp elastic scattering have been measured at kinetic energies of 648, 746, 795, 843, 892, 942 and 992 MeV and for momentum transfer 0.006 < z . sfnctz . sfnc <0.040 (GeV/ c ) 2 . Both scattered and recoil protons were detected in coincidence. The slope parameters of the diffraction cone and the contribution of the spin-spin amplitudes to forward elastic pp scattering were determined.

TheΞ-p differential elastic cross section has been measured in the SPS hyperon beam at 102 and 135 GeV/c. In the range 0.01<−<0.42(GeV/c)2, thet distributions are found to be compatible with the formA exp(Bt) whereB is 7.7±0.4(GeV/c)−2 at 102 GeV/c and 8.2 ±0.5(GeV/c)−2 at 135 GeV/c. The corresponding total elastic cross sections areσel=4.9±0.7 mb andσel=5.6±0.9 mb, respectively. These results are compared with the predictions of phenomenological models.

Differential cross sections for π − p and pp elastic scattering have been measured at incident momenta ranging from 30 to 345 GeV and in the t range 0.002 (GeV/ c ) 2 ⩽ | t | ⩽ 0.04 (GeV/ c ) 2 . From the analysis of the data, the ratio ϱ ( t = 0) of the real to the imaginary parts of the forward scattering amplitude was determined together with the logarithmic slope b of the diffraction cone.

Diffraction scattering of the 17.9 GeV/c alpha particles on hydrogen and helium nuclei

The absolute differential cross sections for ap elastic scattering and for the sum of elastic and quasielastic aa scattering have been measured at a momentum of 17.9 GeV/c in the four-momentum transfer region (0.01 < | t | < 0.2) GeV2/c2 with normalization errors less than 3%. Such measurements in the energy region of a few GeV have been performed for the first time. The measurements have been carried out using the alpha particle beam with the intensity of (1-5)x105 particles/s extracted from the synchrophasotron during 0.3-0.5s. The cryogen target filled with hydrogen (0.847+-0.001 g/cm2) and helium was used. The substance amount along the particle path constituted 0.11 g/cm2 in an unfilled target. The total cross sections, diffraction cone slope parameters and total elastic cross sections for ap and aa scattering have been obtained. The results are compared with the calculations carried out in the frames of the Glauber-Sitenko diffraction multiple scattering theory. The deviation of the calculated differential cross sections from the experimental ones is observed. In the region of the diffraction cone the deviation has a different sign for ap and aa scattering and amounts to 10-15%

SMALL /t/ pi- p CHARGE EXCHANGE SCATTERING AT 40-GeV/c

The Serpukhov-Brussels-Annecy(LAPP) collaboration Binon, F.G. ; Davydov, V.A. ; Donskov, S.V. ; et al.

π−p→π0n differential cross-sections have been measured in the region of small 4-momentum transfer at 40 GeV/c incident momentum. The experiment performed at the IHEP 70 GeV accelerator makes use of a hodoscope γ-spectrometer. Thet- dependence of the cross-section points to a dominance of the spin-flip amplitude.
