Abstract

A theory for tunneling spectroscopy in normal metal /insulator/triplet superconductor junction is presented. We assume two kinds of non-unitary triplet superconducting states which are the most promising states for Sr2RuO4. The calculated conductance spectra showzero-bias peaks as well as gap structures. The existences of residual components in the spectra reflect the non-unitary properties of superconducting states.
