Abstract
The effects of intensity interferometry (HBT), which are mainly reflected by the measured momentum correlations, have been fully discussed since 1950's. The analogous momentum correlations between identical fermions are however less argued. Besides the fermion statistics, the momentum correlations between identical fermions are also determined by some other aspects, such as coulomb interaction, spin interactions and resonances formation. In this paper, we discussed the factors that influence the momentum correlations between $\Lambda$'s, especially spin interaction. It is also argued that the momentum correlations between $\Lambda$'s are affected significantly by the yield ratio of $\Sigma^0/\Lambda$, due to the limitation of experimental measurement. The mixture of $\Sigma^0$'s and $\Lambda$s would significantly weaken the measured two-particle momentum correlations of $\Lambda$'s.
