GLUON DISTRIBUTION AND DF(2) DINQ(2) AT SMALL-X IN THE NEXT-TO-LEADING ORDER/

We obtain an approximate form of gluon momentum density G(x, Q(2)) fro m next to leading order (NLO) CLAP equation at low rx, with a factoriz ation ansatz recently reported and test its validity by comparing it w ith that of Gluck, Reya and Vogt (GRV-HO) which has no such additional assumption. Using Prytz's approximate method, we calculate dF(2)/d lo g Q(2) using LO and NLO forms of gluon density. Limitation of the pres ent formalism is critically discussed and approximate factorizability zone in (x-Q(2)) plane is indicated.
