Schilling %J Physics %D 2000 %I arXiv %X A new H1 measurement of diffractive dijet and 3-jet production cross sections in diffractive deep inelastic scattering events of the type ep->eXY is presented. The data constrain well the diffractive gluon distribution. At low x-pom, a calculation based on perturbative QCD is in a reasonable agreement with the data. %U http://arxiv.org/abs/hep-ex/0012065v2
