We have studied the density of states of the normal state of theelectron-doped superconductor Pr$_{2-x}$Ce$_x$CuO$_4$ at low temperatures andin magnetic fields up to 31 Tesla using point contact spectroscopy on singlecrystals. Our data clearly reveal an anomalous gap in the normal state densityof states. This normal state gap survives even in the highest applied field of31 T. Our results cast doubt over whether this gap found in electron-dopedcuprates is the analog of the pseudogap in hole-doped cuprates. We havesuggested an alternate origin of the normal state gap, which involves theeffect of disorder and electron correlations at the surface of cuprates.
