Abstract
A leading order determination of the gluon density in the proton has b een performed in the fractional momentum range 1.9 . 10(-3) < x(g/p) < 0.1.8 by measuring multi-jet events from boson-gluon fusion in deep-i nelastic scattering with the H1 detector at the electron-proton collid er HERA. This direct determination of the gluon density was performed in a kinematic region previously not accessible. The data show a consi derable increase of the gluon density with decreasing fractional momen ta of the gluons.
