The strength distribution as a function of the excitation energy is investigated in the framework of the Quasiparticle Random Phase Approximation. The results are compared with the available experimental data for and with the results of recent shell model calculations. It is demonstrated that the full single-particle space has to be used in order to describe the GT strength function correctly.
