Abstract
The utility of prompt photon plus associated jet production for constr aining the size and shape of the polarized gluon density of the proton Delta G is examined at root S = 40 GeV, appropriate for the proposed HERA-(N) over right arrow polarized (p) over right arrow (p) over righ t arrow collider experiment. The calculation is performed at next-to-l eading order (O(alpha alpha(s)(2))) in QCD. The reliability of the pre dictions are examined in some detail. (C) 1997 Elsevier Science B.V.
