Abstract
Experimental results for Cu(110) and Ni(110) pointed out anharmonicity as precursor of surface roughening. This was also supported by recent results of molecular dynamics simulations. On the contrary the presen ce of anharmonicity was nor detected on Ag(110) in similar conditions. This paper presents preliminary results on the energy shifts and tile linewidths of surface phonons obtained by means of energy resolved He atom scattering in order to solve the apparent contradiction.
