  A search has been performed for the experimental signature of an isolated
photon with high transverse momentum, at least one jet identified as
originating from a bottom quark, and high missing transverse momentum. Such a
final state may originate from supersymmetric models with gauge-mediated
supersymmetry breaking in events in which one of a pair of higgsino-like
neutralinos decays into a photon and a gravitino while the other decays into a
Higgs boson and a gravitino. The search is performed using the full dataset of
7 TeV proton-proton collisions recorded with the ATLAS detector at the LHC in
2011, corresponding to an integrated luminosity of 4.7 fb-1. A total of 7
candidate events are observed while 7.5 pm 2.2 events are expected from the
Standard Model background. The results of the search are interpreted in the
context of general gauge mediation to exclude certain regions of a benchmark
plane for higgsino-like neutralino production.
