Abstract: Many authors have studied the rate of average decay of the Fourier transform of measures because of its relationship with the Falconer's conjecture. Although examples have been given showing that the spherical average of the Fourier transform cannot decay always too fast, they usually do not exhibit a single measure decaying sufficiently slow on the whole space. We recover known results using instead single measures.
