Abstract
An experimental investigation was made of the optical absorption spectra corresponding to transitions in the Pr3+ ion in crystalline LaF3 matrices. The investigation was carried out in the temperature range 5 divided by 80 K. An anomalous redistribution of the intensity was observed in the absorption spectrum of a Pr3+:LaF3 crystal. This redistribution did not agree with the hypothesis of the Boltzman population of the states in discrete multilevel systems.
