·Òë 1. Hydrogen induced missing row reconstruction of Fe(211) 2.The analysis of the clean surface confirms and determines with high accuracy the presence of a registry shift between the first two layers of Fe(211) in addition to the oscillatory multilayer relaxation usually observed for non close packed metal surfaces. £¨registry shift £© 3. There is considerable pairing of rows and buckling of layers. 4.This allows high speed measurements of I(E) spectra with a maximum rate of one intensity data point per energy and beam within the time of a video half frame¡£ 5.In addition to the 9 integer order spots 6 half order spots were measured resulting in a data base of total energy width A E =2260eV 6.The shift brings the surface atoms nearer to 3-fold coordination with second layer atoms¡£ |
