Wehave observed phase separation between the superfluid and the normalcomponent in a strongly interacting Fermi gas with imbalanced spinpopulations. The in situ distribution of the density difference between twotrapped spin components is obtained using phase-contrast imaging and 3Dimage reconstruction. A shell structure is clearly identified where thesuperfluid region of equal densities is surrounded by a normalgas of unequal densities. The phase transition induces a dramaticchange in the density profiles as excess fermions are expelledfrom the superfluid.
