Improved but low-x approximated relation between F-2(p) scaling violation and gluon momentum distribution function

We present a brief analysis on the approximate methods for the determinatio n of gluon distribution from the scaling violation of proton structure F-2( P) in the low-x limit. In the leading order, a general low-x approximated r elation is presented having more accuracy than the previous methods. Next-t o-leading order correction is presented incorporating double log-approximat ion. The proposed method is found to give good agreement with data. It may also be used to discriminate between the sets of gluon distributions in the low-x.
