Reliable, with one-point correction of energy scale
Comment:
2 L CH3OH were adsorbed onto NiAl at 150 K and heated to 650 K. The substrate was cleaned by cycles of Ar+ ion bombardment (Ep = 2 keV), and annealing (T = 1073 K, time = 10 min). Carbon was removed from NiAl by heating in 1E-7 torr of O2 at 1000 K.
