[9, 11, 63, 64] and d the 4f 5/2 spectra for the Re(0001) and Re(1231) skins [66, 67] collected at
e 0° and f 75° polar angles. The relative change of the S 3 /B intensity with emission angle evidences
the positive SCLS. Table 4.4 features the derived information. Reprinted with permission from [29,

layer is lower than the value of 3.50 for the Re(0001) top layer. The low-energy tails
in Fig. 4.11 correspond to the quantum entrapment of the even lower coordinated
defects or edge atoms.
