Reliable (reported energy within 300 eV of a reference energy)
Comment:
0.075-1.2 ML Sn/n-type Si(100). The Sn overlayers were prepared by electron beam evaporation. Substrate temperature was 423-473K. The deposited surface were annealed at 823 K for 2 min. and allowed to cool to 373-423K before measurements. Branching ratio is 0.74.
