Differential cross-sections for pp elastic scattering in the transfer momentum range 2 x 10 −3 ⩽ | t| ⩽ x8 10 −3 (GeV/ c) 2 were studied with a hydrogen filled ionization chamber which was used as a target and as a detector of the recoiled protons. The measurements have been done at P lab. = 1.11 GeV/ c, 1.28 GeV/ c, 1.34 GeV/ c, 1.40 GeV/ c and 1.70 GeV/ c. The real part of the spin independent forward scattering amplitude has been determined, the results being in agreement with the dispersion relation calculations.
