摘要：

We report on tunneling spectroscopy measurements using a scanning tunneling microscope (STM) on the spin triplet superconductor Sr2RuO4. A fully open gap, close to the Bardeen-Cooper-Schrieffer (BCS) value, is found, which disappears at the bulk T-c = 1.5 K. The results are discussed in the framework of recent multigap scenarios for an unconventional spin triplet superconductor.
