Measurements of the Total $\pi$ He and $p$ He Cross-sections and the Slopes of the Forward Diffraction Peak at Energies From 50-{GeV} to 300-{GeV}

Differential cross sections for elastic scattering of pions and protons on helium have been measured at incident momenta ranging from 50 to 300 GeV/ c in the t -range 0.008 < | < | < 0.05 (GeV/ c ) 2 . Both recoil α-particles and forward particles were detected in this experiment. The experimental method provided an absolute normalization of the cross sections with an estimated precision of 1%. From the analysis of the data, the diffraction slope parameters and total cross sections have been obtained. The results are compared with Glauber model calculations.
