The construction and characterization of a focusing X‐ray spherical analyzer based on α‐quartz 404 are presented. The performance of the analyzer was demonstrated by applying it to a high‐resolution X‐ray spectroscopy study of the K α 1,2 emission spectrum of Ni. An analytical representation based on physical grounds was assumed to model the shape of the X‐ray emission lines. Satellite structures assigned to 3 d spectator hole transitions were resolved and determined as well as their relative contribution to the emission spectrum. The present results on 1 s −1 3 d −1 shake probabilities support a recently proposed calculation framework based on a multi‐configuration atomic model.
