摘要：

By using the scanning tunneling microscope we have determined the probability distribution for the distances between steps on the Cu(100) surface and the vicinal surfaces (11n) with n = 7 and 19. The results indicate a repulsive short-range step-step interaction, however, unexpectedly, an attractive interaction at intermediate distances of 3-5 atoms.
