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.},
