    The cross section for the diffractive deep-inelastic scattering process ep → eXp is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data sample covers the range x ℙ <0.1 in fractional proton longitudinal momentum loss, 0.1<| t |<0.7 GeV 2 in squared four-momentum transfer at the proton vertex and 4< Q 2 <700 GeV 2 in photon virtuality. The cross section is measured four-fold differentially in t , x ℙ , Q 2 and β = x / x ℙ , where x is the Bjorken scaling variable. The t and x ℙ dependences are interpreted in terms of an effective pomeron trajectory and a sub-leading exchange. The data are compared with perturbative QCD predictions at next-to-leading order based on diffractive parton distribution functions previously extracted from complementary measurements of inclusive diffractive deep-inelastic scattering. The ratio of the diffractive to the inclusive ep cross section is studied as a function of Q 2 , β and x ℙ .
