Abstract

Electron tunneling experiment on novel superconductor LaSrCuO system with the transition temperature of about 35K has been carried out by point contact method. The observed electronic density of states is smeared out compared with the BCS one. The energy gap seems to be larger than 3.52kTc expected by BCS theory. Based on these results, the superconducting properties of the system are discussed.
