Fig. (16) Resolution function of the toroidal magnetic spectrometer at Zurich University [123]. The solid line with the resolution of 17.0 eV (FWHM) was derived from the measured L₁ conversion-electron line of the 30.898 keV transition in ¹⁹⁵Au (Γ = 6.25 eV). Points were obtained from a Monte Carlo simulation.
