Angle- and spin-resolved photoelectron spectroscopy of the 4f subshell in atomic ytterbium

Svensson A, Müller M, Böwering N, Heinzmann U, Radojevic V, Wijesundera W. Angle- and spin-resolved photoelectron spectroscopy of the 4f subshell in atomic ytterbium. Journal of Physics B: Atomic, Molecular and Optical Physics. 1988;21(8):L179-L185.The spin polarisation components of photoelectrons from atomic ytterbium have been measured over the photon energy range from 15.5 to 22.5 eV. The measurements were performed by making use of circularly polarised synchrotron radiation from the storage ring BESSY in conjunction with an angle-resolved electron spectrometer. Theoretical predictions based on the relativistic random-phase approximation (RRPA) are in fair agreement with the experimental data even though a certain offset between theory and experiment exists
