  Superfluid 3He confined to high porosity silica aerogel is the paradigm
system for understanding impurity effects in unconventional superconductors.
However, a crucial first step has been elusive; exact identification of the
microscopic states of the superfluid in the presence of quenched disorder.
Using a new class of highly uniform aerogel materials, we report pulsed nuclear
magnetic resonance experiments that demonstrate definitively that the two
observed superfluid states in aerogel are impure versions of the isotropic and
axial p-wave states. The theoretically predicted destruction of long-range
orbital order (Larkin-Imry Ma effect) in the impure axial state is not
observed.
