Fig. 5. (Color online) The Tan contact vs. the scaled interaction strength calculated from different methods. The green line is from fitting the momentum distribution tail, the blue line is from correlation with Eq. (7), the red line is exact BA results with Eq. (10). The left side of zero is attractive regime where three lines are almost the same, right side of zero is repulsive regime. Inset: the plot of momentum distribution of the major component for a system with $g/2k_{F}=0.5$. The straight line is a fitting function in form $\propto1/k^4$ with the regime $50k_{F}<k<100k_{F}$.
