Effective attenuation length from core-level photoelectron spectroscopy of CS2 clusters

The effective attenuation length (λ) is determined to 5.7 ± 1.1 A at an electronic kinetic energy of 30 eV for carbon disulfide, CS2, from sulphur 2p photoelectron spectroscopy and lineshape modelling of CS2 clusters at a temperature of 150–170 K. The present approach is based on exploring the relation between λ and the cluster–monomer chemical shift and width of the cluster peak. A priori knowledge of the cluster temperature is required.
