dc.description.abstract t has previously been established that the lowest energy site for chlorine atoms on Cu(111) is the fcc hollow. However, substantial population of the hcp hollow at room temperature indicates that there is a relatively small difference in energy between the two sites. We show that this energy difference must be less than 10 meV by measuring the relative populations using normal-incidence x-ray standing waves and comparing the results to Monte Carlo simulations. This result is consistent with recent density functional theory calculations which indicate an energy difference of approximately 5 meV en_US
