EXPERIMENTAL SETUP FOR THE STUDY OF ELASTICπp SCATTERING AT SMALL ANGLES FOR ENERGIES OF 40 AND 50 GEV

摘要

The experiment was performed using a magnetic spectrometer with magnetostrictive spark chambers. Elastic interactions sere identified with the help of the momentum measurement on the scattered π- meson. The four-momentum transfer was determined from the scattering angle in the target. The obtained experimental data allow the determination of the slope of the differen¬tial cross section as a function of the four-momentum transfer. In the region of small by taking into account the interference of the amplitudes of elastic and Coulomb scattering, it is possible to determine the ratio of the real and imaginary parts of the elastic scattering amplitude. The determination of these two parameters is Important for verification of existing predictions about their asymptotic behaviour.
