The electron - phonon coupling strength for two different surface states on Bi(110) close to the Fermi level is determined by measuring the energy- and temperature-dependent imaginary part of the self-energy and fitting it to different models of the phonon spectrum. For the hole pockets near the (Gamma) over bar and (M) over bar points, the electron - phonon mass enhancement parameter. is found to be 0.19( 3) and 0.27(2), respectively.
