摘要：

We have measured-rho, the ratio of the real to the imaginary part of the ppBAR forward elastic-scattering amplitude, at square-root s = 1.8 TeV. Our result, rho = 0.140 +/- 0.069, is compared with extrapolations from lower-energy data based on dispersion relations, and with the UA4 value at square-root s = 546 GeV.
