Observation of small angle proton proton elastic scattering at 30 gev and 45 gev center-of-mass energies

Small angle elastic scattering events have been observed at the CERN Intersecting Storage Rings. Directions of both particles as well as the collision vertex are reconstructed with the help of four sets of spark chambers, two for each of the two arms. The elastic nature of the events is demonstrated by a collinearity requirement. We find values for the (diffraction) slope parameter in disagreement with the simple linear extrapolation of lower energy (Surpukov) data.

Interactions of 14 GeV protons with free and quasi-free nucleons are studied in nuclear emulsion. The elastic cross-section for proton-free proton collision is estimated to be (11±4) mb. The numbers of protons, charged π-mesons and K-mesons per inelastic interaction are found to be 1.24±0.09, 2.53±0.19 and 0.30±0.06, respectively. The centre-of-mass system angular distributions and the mean values of the centre-of-mass system momenta for charged secondaries are given and compared with the results of works at other energies.
