N2 - We analyzed photoemission data for several doping levels of the (Formula presented) compounds, ranging from overdoped to underdoped. We show that the high frequency part of the spectra near (0,π) can be described by Fermi liquid theory in the overdoped regime, but exhibits a non-Fermi liquid behavior in the underdoped regime. We further demonstrate that this behavior fits reasonably well to a (Formula presented) behavior suggested for systems with strong spin fluctuations.
