N2 - The value of the η-η′ mixing angle θp is phenomenologically deduced from a rather exhaustive and up-to-date analysis of data including strong decays of tensor and higher-spin mesons, electromagnetic decays of vector and pseudoscalar mesons, J/ψ decays into a vector and a pseudoscalar meson, and other transitions. A value of θp between -17° and -13° is consistent with the present experimental evidence and the average θp = -15.5° ± 1.3° seems to be favoured.
