Comment:

0.25 ML Rb/ Al(111)-(2x2) and 0.33 ML Rb/Al(111)-(R3xR3). The Al(111) crystal was cleaned by cycles of Ar+ ion bombardment and annealing (T = ~700 K). The spectra were recorded at normal emission.

cooled, crystal, surface coverage from 0ML to 1ML (0ML < coverage < 1ML), thin layer, vapor deposited
