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 × 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 × 1)O and Ni(110)‐ c (2 × 2)S along the line of the Ni(110) surface Brillouin zone have been studied.
