heal.abstract	Thermally stimulated depolarisation current measurements on hydrated lysozyme powder in the temperature range 77-300 K and water content range 0.07-0.29 water/g dry protein show a broad low-temperature peak in the range 100-160 K and a complex high-temperature band in the range 160-300 K. Four dispersions were found to contribute to the high-temperature band, the α2-dispersion, the α-dispersion, the Ω-dispersion and a 'new' dispersion. The α-dispersion and the new dispersion occurring in the same temperature range were studied in detail. The activation energies of the α-dispersion and the new dispersion were determined. Both dispersions are characterised by distributions of relaxation times and activation energies.	en
