  A search for the decay of a light Higgs (120 - 140 GeV) to a pair of
weakly-interacting, long-lived particles in 1.94 fb^-1 of proton-proton
collisions at sqrt{s} = 7 TeV recorded in 2011 by the ATLAS detector is
presented. The search strategy requires that both long-lived particles decay
inside the muon spectrometer. No excess of events is observed above the
expected background and limits on the Higgs boson production times branching
ratio to weakly-interacting, long-lived particles are derived as a function of
the particle proper decay length.
