abstract_translated_text: A measurement is presented of dijet and 3-jet cross sections in low-t  diffractive deep-inelastic scattering interactions of the type ep->eXY, where the system X is separated by a large rapidity gap from a low-mass baryonic  system Y. Data taken with the H1 detector at HERA, corresponding to an integrated luminosity of 18.0 pb-1, are used to measure hadron level single and double differential cross sections for 4<Q^2<80 GeV^2, x-pom<0.05 and pT-jet>4 GeV. The energy flow not attributed to jets is investigated. Viewed in terms of the diffractive scattering of partonic fluctuations of the photon, the data require the dominance of q-qbar-g over q-qbar states.   The measurements are consistent with a factorising diffractive exchange with  an intercept close to 1.2  and tightly constrain the dominating diffractive  gluon distribution. Soft colour neutralisation models in their present form  cannot simultaneously reproduce the shapes and the normalisations of the  differential cross sections. Models based on 2-gluon exchange are able to  reproduce the shapes of the cross sections at low x-pom values.
