(for the ALICE Collaboration) The relative rates of single‐ and double‐ diffractive processes were measured with the ALICE detector by studying properties of gaps in the pseudorapidity distribution of particles produced in proton‐proton collisions at \sqrt{s} = 0.9 TeV, 2.76 TeV and 7 TeV. ALICE triggering efficiencies were determined for various classes of events, using a detector simulation validated with data on inclusive particle production. Cross‐sections were determined using van der Meer scans to measure beam properties.
