Recent advances in random matrix theory enable one to determine the pseudoscalar decay constant from the dependence of the eigenvalues of the valence Dirac operator on an imaginary isospin chemical potential. We perform a pilot test of this idea, from simulations with two flavors of dynamical overlap fermions.
