Tunneling measurements have been carried out on heavily
underdoped and slightly overdoped
(
) single crystals by using a break-junction technique. We find
that in-plane tunneling spectra below 
are the
combination of incoherent part from the pseudogap and coherent
quasiparticle peaks. There is a correlation between the
magnitude of the pseudogap and the magnitude of the
superconducting gap in . We find that the quasiparticle
conductance peaks are caused by condensed soliton-like excitations.
