  Interlayer tunneling spectroscopy measurements were performed on mesa arrays
of Bi-2212 single crystals, intercalated with HgBr$_2$. Tunneling conductances
were obtained over a wide temperature range to examine the spectral features,
especially the behavior of the quasiparticle peaks corresponding to
superconducting energy gaps (SGs). Experimental spectra showed that gap-like
features are still present even for the temperatures far above the transition
temperature, T$_c$. This evidence is consistent with the idea that the SG
evolves into a pseudogap above T$_c$ for HgBr$_2$-intercalated Bi-2212 single
crystals.
