Abstract
With the help of a combined LEED- and Auger-investigation, the surface of a platinum (111) crystal was cleaned first. Then, the spectrum of the characteristic energy losses for both contaminated and cleaned surfaces is studied. On the cleaned surface the following losses were found: ΔE 1=7.4 eV, ΔE 2=13.5 eV, ΔE 3=24.8 eV, ΔE 4=31.8 eV, ΔE 5=45.1 eV, ΔE 6=54.1 eV, ΔE 7=71.2 eV.
The present results are compared with the measurement of other investigators. In particular, in good agreement with optical measurements we identify ΔE 1 and ΔE 2 as interband transitions, and ΔE 3 and ΔE 4 as surface and volume plasma loss, respectively.
