We report results of inclusive measurements of <(Lambda)over bar>degrees, produced in the forward direction at the Sp (p) over bar S with root s= 630 GeV, using the UA8 small angle Roman Pot spectrometers. These measurements cover the range in Feynman-x(F) and transverse momentum, 0.6 < x(F) < 1.0 and 0.4 < p(t) < 0.7 GeV, respectively. Within a systematic uncertainty of +/-20% on the absolute cross section measurements, the results are indistinguishable from those made by some of us in two earlier experiments at the CERN Intersecting Storage Rings, with energies, root s = 53 and 62 GeV. In the x(F)-range, 0.6-0.9, the absolute cross sections are lower by a factor of 2 to 3 than the predictions of the Lund model as embodied in the PYTHIA 5.6 and JETSET 7.3 Monte Carlo programs, indicating inadequacies in knowledge of the baryon fragmentation function, For the largest x(F)-range, 0.9-1.0, the measurements agree with the Monte Carlo predictions. We have measured the average <(Lambda)over bar>degrees polarization for our events and find (6+/-12%), consistent with previous measurements at the ISR in the present region of x(F)-p(t).
