Observation of the resonant two-hole bound state at the 3p-core threshold in Zn and Zn-phthalocyanine
Abstract
Photoelectron energy distribution curves obtained with photon energies near the 3p threshold (hν ≈ 90 eV) for Zn metal and Zn-phthalocyanine (Zn-Pc) show pronounced resonance satellite structures at about 20 eV below the Zn 3d main peak. The experiments demonstrate clearly the occurrence of resonant two-hole bound states even in the presence of filled 3d shells and stress the importance of empty s-like states for the satellites in 3d metals. © 1980.
