摘要：
It is suggested that for a Fermi gas at unitarity, the two-body bond plays a special role. We propose an equation of state using an ansatz relating the interaction part of the l-body cluster to its two-body counterpart. This allows a parameter-free comparison with the recently measured equation of state by the ENS group. The agreement between the two over a range of fugacity (z < 5 for a homogeneous gas, and z < 10 for the trapped gas) leads us to perform the calculations of more sensitive quantities measured recently by the MIT group.
