A new compact spin- and angle-resolving photoelectron spectrometer with a high efficiency.
A portable spin- and angle-resolving photoelectron spectrometer has been constructed, equipped with a newly developed compact retarding-potential Mott-scattering electron spin polarimeter with an efficiency of 1.9 x 10(-4) for a gold target. Based on Monte Carlo calculations for the spin-dependent electron-scattering process and electron ray-tracing calculations, a novel design of the retarding-field electron optics with 0.59 sr collection solid angle for scattered electrons has been accomplished. Utilizing this spectrometer, the spin- and angle-resolved photoelectron spectra have been measured and the spin-dependent electronic structure of Ni(110), Ni(110)-p(2 x 1)O and Ni(110)-c(2 x 2)S along the ${\overline {\Gamma S}}$ line of the Ni(110) surface Brillouin zone have been studied.
