The present paper is based on 378 elastic scattering events in the incident-momentum region 120-320 . Differential and total cross sections have been measured in several momentum intervals and found to be consistent with predominantly -wave scattering. No significant indication for the existence of a low-energy resonance has been found. Using the effective-range approximation, the four scattering parameters , , , and were evaluated with and without further assumptions on the interaction properties. Best values obtained from the four-parameter fit were , , , and F. A likelihood-function mapping procedure is used to describe the large and strongly correlated errors of these values.
