The evolution of orbital angular momentum distributions within the radiative parton model is studied. We use different scenarios for the helicity weighted parton distributions and consider a broad range of input distributions for orbital angular momentum. In all cases we are lead to the conclusion that the absolute value of the average orbital angular momentum per parton peaks at relatively large x approximate to 0.1 for perturbatively accessible scales, Furthermore, in all scenarios considered here the average orbital momentum per parton is several times larger for gluons than for quarks which favours gluon initiated reactions to measure orbital angular momentum. The large gluon polarization typically obtained in NLO-fits to DIS data is in each case primarily canceled by the gluon orbital angular momentum. (C) 1999 Elsevier Science B.V. All rights reserved.
