  "abstract": "A phenomenological analysis on various decay processes is performed using an energy-dependent $\\eta-\\eta'$ mixing angle scheme. Special attention is given to the radiative couplings between lowest-lying vector and pseudoscalar mesons. The agreement between our predictions and the experimental values is remarkable. This analysis opens a connection to two-angle fits in the $\\eta-\\eta'$ sector.",
