The electronic structure of the charge-density wave (CDW) and superconducting dichalcogenide, 2H-NbSe2 was studied using high-resolution photoemission. Important components of the quasiparticle interactions were identified from the extracted self-energies. A strong anisotropy of the self-energy was detected. The strongest electron-phonon coupling was found on the inner K-H cylinder, which played a major role in both CDW and superconductivity (SC) transitions.
