Description

The linewidth method for determining the f-factor for 151Eu compounds has been developed. It is shown that, for these compounds, the relation between spectral linewidth and sample thickness usually assumed: Γ(t)= Γs + Γa + 0.27 Γn t (Γn = natural linewidth of the isotope) has to be changed to Γ(t) = Γs + Γa + 0.23 Γa t (Γa = absorber spectral linewidth extrapolated at t=0). A comparison of the f-factor results for the case of the 151Eu in EBCO superconductor obtained by using the absolute absorption area method and the linewidth method is performed. (orig.)
