✦ Synopsis
The dependence of satellite structure in the atomic UV photoelectron qectra of Zn, Cd and fig on photon wav&nptb has been examined by usmg both HcI 584 A and Hell 304 A sources. Apart from work on tie and wme qualitative observetions on other atoms, there have prcvvlously been no studies on the wavelength dependence of correlation satellite intcnsitics. The main lines m the spectra correspond to (n -l)dlo~?s; *S ,i2 and (fl --I)dgnsL; 2Ds/2 and *D3j2 fmJ states, and the satellites are the (n -l)d'Onp; 2Pt/2, 2P312 lines. The relative intenslticsof the satelliteswith respect to that of ths 'Sr/z line arc found to be essentially independent of photon energy for all three Group iIB atoms. strondy sugestinn that their intensity is due in each case to the imtial state configuration interaction (KC0 mechanism. This result is consistent with the near degeneracy of the ns and np shell energies, which facilitates strong admrhture of the configuration (n -I )d"#~p'; 'S into the ground state of these atoms.
