Summary
Electron paramagnetic resonance spectra of crystals of NaCl: Mn show eight different well-resolved paramagnetic centres. The relaxation of the centres is studied by observing the time variation of the intensities of the resonance lines at different temperatures. The kinetics of the relaxation process has been established and a measurement of the activation energy for the various types of interactions is given.
Riassunto
Gli spettri della risonanza paramagnetica elettronica dei eristalli di NaCl:Mn presentano otto diversi centri paramagnetici ben risolti. Si studia il rilassamento dei centri osservando la variazione nel tempo delle intensità delle linee di risonanza a differenti temperature. Si è definita la cinetica dei processi di rilassamento e si riporta una misura dell’energia di attivazione per i vari tipi di interazione.
