摘要：
The moment of inertia Theta of a trapped superfluid gas of atomic fermions (Li-6) is calculated as a function of the temperature. At zero temperature the moment of inertia takes on the irrotational-flow value. Only for T very close to Te is rigid rotation attained. It is proposed that future measurements of the rotational energy will unambiguously reveal whether the system is in a superfluid state or not.
