N2 - A mean-field potential is derived for an excess electron near a (4He)N cluster, which incorporates a realistic description of the cluster surface profile. Calculations of the energies for the ground state and electronically excited surface states were performed. Over a broad cluster size domain (N=107109) the binding energies are systematically lower (i.e., by 610 % for the ground state and by 1020 % for electronically excited states) than those based on model potentials, which represented the interaction within the cluster interior in terms of the conduction-band energy of the liquid.
