A measurement is presented of the two-jet differential cross
section, d3 sigma/dE(t) d eta_1 d eta_2, at center of mass energy s**(1/2) =
1800 GeV in p anti-p collisions. The results are based on an integrated
luminosity of 86 pb-1 collected during 1994-1995 by the CDF collaboration
at the Fermilab Tevatron collider. The differential cross section is
measured as a function of the transverse energy, E(t), of a jet in the
pseudorapidity region 0.1 < |eta_1| < 0.7 for four different pseudorapidity
bins of a second jet restricted to 0.1 < |eta_2| < 3.0. The results are
compared with next-to-leading order QCD calculations determined using the
CTEQ4 and MRST sets of parton distribution functions. None of the sets
examined in this analysis provides a good description of the data.
