Crystal nucleation in the one-component metals Ni and Au is investigated using a combination of differential thermal analysis (DTA) experiments and Monte Carlo (MC) simulations. A novel experimental methodology allows to measure nucleation rates J over a range of 8 orders of magnitude. Evidence is given that these rates correspond to homogeneous nucleation. From the nucleation rates, free energy nucleation barriers Delta G (a
