Abstract
An experimental investigation was made of the optical absorption spect ra representing transitions in the Pr3+ ion in crystalline LaF3 and Y2 SiO5 matrices The investigation was carried out in the temperature ran ge 5-80 K. An anomalous redistribution of the intensity was observed i n the absorption spectrum of a Pr3+:LaF3 crystal. This redistribution did not agree with the hypothesis of the Boltzmann population of the s tates in discrete multilevel systems.
