We apply the formulation developed in a recent paper [Y. Ohashi and A.
Griffin, Phys. Rev. A {\bf 72}, 013601, (2005)] for single-particle excitations
in the BCS-BEC crossover to the case of a broad Feshbach resonance. At T=0, we
solve the Bogoliubov-de Gennes coupled equations taking into account a Bose
condensate of bound states (molecules). In the case of a broad resonance, the
density profile n(r), as well as the profile of the superfluid order
parameter Δ~(r), are spatially spread out to the Thomas-Fermi
radius, even in the crossover region. This order parameter Δ~(r)
suppresses the effects of low-energy Andreev bound states on the rf-tunneling
current. As a result, the peak energy in the rf-spectrum is found to occur at
an energy equal to the superfluid order parameter Δ~(r=0) at the
center of the trap, in contrast to the case of a narrow resonance, and in
agreement with recent measurements. The LDA is found to give a good
approximation for the rf-tunneling spectrum.Comment: 14 pages, 8 figure
