Abstract
The possibility of observing resonance superfluidity by a probing field transferring atoms out of the superfluid was analyzed. It was shown that the emergence of the pseudogap obscures the phase transition signature because it makes the transfer resonance peak asymmetric even above Tc. It was found that the shape of the peak is asymmetric due to the single particle excitation gap. The results show that the incoherent nature of the noncondensed pairs leads to broadening of the peak.
