Query: Charge-Density-Wave induced modifications to the quasiparticle
  self-energy in 2H TaSe2   The self-energy of the photo-hole in 2H-TaSe2 is measured by angle-resolved
photoemission spectroscopy (ARPES) as a function of binding energy and
temperature. In the charge-density wave (CDW) state, a structure in the self-
energy is detected at ~ 65 meV that can not be explained by electron-phonon
scattering. A reduction in the scattering rates below this energy indicates the
collapse of a major scattering channel with the formation of the CDW state,
accompanying the appearance of a bosonic "mode" in the excitation spectrum of
the system.
