摘要：

A leading order determination of the gluon density in the proton has been 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-inelastic scattering with the H1 detector at the electron-proton collider HERA. This direct determination of the gluon density was performed in a kinematic region previously not accessible. The data show a considerable increase of the gluon density with decreasing fractional momenta of the gluons.
