Abstract

New low-temperature vibronic Raman and EPR (under stress) spectra on CaF₂:La²⁺ are reported. The experimental data are interpreted as indicating the presence of an intermediate E(X) epsilon type of Jahn-Teller coupling. The lowest vibronic state is approximately=15 cm^-1 below the top of the angular barrier.
