Abstract
The ground state of a two-level system coupled to a dispersionless phonon bath is studied by the coupledcluster method. The estimates of both the ground-state energy and the tunneling reduction factor are found to be in good agreement with the exact values. It is also found that within the coupled-cluster approximation there is no indication of the discontinuous localization-delocalization transition. This is consistent with the exact result. @S0163-1829~96!08042-3#
