Abstract

The study of the superconducting-gap of MgB₂ with the help of high resolution angle resolved photoemission spectroscopy was presented. It was shown that the superconducting gaps with values of 5.5 and 2.2 meV open on the σ band and the π band. The σ and π-band superconducting gap values agreed well with the previous angle-integrated (AI) PES results.
