Abstract
In the commented paper an estimation of parameters for the atom-surface int eraction potential for the system (HeNaCl)-He-4(0 0 1), is presented. In th is comment, the validity of the arguments on which the estimation is founde d is discussed. It is concluded that the arguments are incorrect. It is als o shown that the estimated parameters yield a repulsive interaction potenti al, therefore, the bound states reported in the commented paper can not be obtained from a correct calculation.
