At the critical point it is still quite large: ξ ( z$_{c}$ ) = 12 . 6. 

The ratio η/s reaches its minimum near z$_{c}$ , and is quite large compared to the attractive case: 

## B. Repulsive Bosons 

<img src='content_image/347520.jpg'>

The repulsive boson case is similar to the repulsive fermion, except that now there are only positive density solutions to the eq. (83) for µ/T < − log 2. Figure 22 compares the density for bosons verses fermions. The maximum density for bosons, which could again possibly signify a critical point at z$_{c}$ ≈ e − 1 . 45 = 0 . 235, is half that
