摘要：

We have used Spin Polarized Low Energy Electron Diffraction (SPLEED) to probe the short range order at a Pb(110)-surface during melting. We find that the short range order in the top two surface layers changes discontinuously at TS = 524 ± 1 K, i.e. the top layers melt via a first order phase transition. © 1990.
