      abstract     = {We have investigated the ferromagnetic phase transition of
                      elemental Co by high-resolution neutron backscattering
                      spectroscopy. We monitored the splitting of the nuclear
                      levels by the hyperfine field at the Co nucleus. The energy
                      of this hyperfine splitting is identified as the order
                      parameter of the ferromagnetic phase transition. By
                      measuring the temperature dependence of the energy we
                      determined the critical exponent and the ferromagnetic Curie
                      temperature of K. The present result of the critical
                      exponent agrees better with the predicted value (0.367) of
                      the three-dimensional Heisenberg model than that determined
                      previously by nuclear magnetic resonance.},
