      abstract     = {The proton--proton elastic differential cross section at
                      very small four momentum transfer squared has been measured
                      at three different incident proton momenta in the range of
                      2.5 to 3.2 GeV/c by detecting the recoil proton at polar
                      angles close to 90∘. The measurement was performed at COSY
                      with the KOALA detector covering the Coulomb-nuclear
                      interference region. The total cross section σtot, which
                      has been determined precisely, is consistent with previous
                      measurements. The values of the slope parameter B and the
                      relative real amplitude ratio ρ determined in this
                      experiment alleviate the lack of data in the relevant energy
                      region. This precise data on ρ might be an important check
                      for a new dispersion analysis.},
