Abstract

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.

    An active target IKAR was also used for the high-energy scattering of He and Li halo nuclei. IKAR is the hydrogen-filled ionization chamber developed by PNPI Gatchina [49–51]. Measurements of interaction cross sections and reaction cross sections have been the main method for determining the matter radii of short lived nuclei.
