We present the first measurement of two-particle momentum
correlations in jets produced in p anti-p collisions at s**(1/2) =
1.96 TeV. Results are obtained for charged particles within a restricted
cone with an opening angle of 0.5 radius around the jet axis and for
events with dijet masses between 66 and 563 GeV/c2. A comparison of the
experimental data to theoretical predictions obtained for partons within
the framework of resummed perturbative QCD in the next-to-leading log
approximation (NLLA) shows that the parton momentum correlations survive
the hadronization stage of jet fragmentation, giving further support to
the hypothesis of local parton-hadron duality. The extracted value of
the NLLA parton shower cutoff scale Q_eff is found to be (1.4+0.9_-0.7)
x 100 MeV.
