Appearance potential spectra have been measured for (low-temperature) hcp and and (high-temperature) fcc cobalt. The transition temperatures are found to be 690+/-6 K for the hcp to fcc transition and 653+/- 12 K for the fcc to hcp transition, in good agreement with earlier findings. Critical point energies are 6.7+/-0.3 eV for the M point in hcp cobalt, 5.6+/-0.3 eV for the L(7) and 8.9+/-0.3 eV for the X(7), K(8) critical points in fcc cobalt, respectively.
