On a déterminé la probabilité d'absorption sans recul de photons γ par des petites particules de fer en fonction de la température. Les particules sont enrobées dans des matrices diverses. Pour des particules de taille supérieure ou égale à 100 Å, la température de Debye n'est pas vraiment différente de celle du matériau massif, dans la limite de quelques %.The probability of recoilless absorption of γ-quanta by small particles of iron metal embedded in various matrices was determined as function of temperature. The analysis of the result revealed that, for the particles with diameter > ≈ 100 Å, the Debye temperature does not differ from the bulk value by more than several percent
