The results of ultrasonic studies of a crystal with a fluorite structure CdF₂ doped with low concentration chromium atoms (n_Cr=6.3·10¹⁹ cm^-3 with a predominance of Cr³⁺ ions were presented. The measurements were performed in the range of 3.6-150 K at frequencies 18-268 MHz using transverse and longitudinal normal modes propagating in the crystallographic direction [100]. The anomalies characteristic for systems of Jahn-Teller cubic complexes with orthorhombic minima of the adiabatic potential have been discovered in the temperature dependence of the attenuation and velocity of ultrasonic waves. The interpretation of the results was carried out in the framework of the quadratic T ⊗ (e+t₂) problem of the Jahn-Teller effect for Cr²⁺ $F_{8}^{-}$ complexes, whose concentration was of the order of 10^-2 n_Cr. The analysis of the experimental data made it possible to determine the configurational relaxation mechanisms of the Jahn-Teller subsystem and the values of the parameters that determine them.
