Abstract

Averaging effects produced by relaxation have been observed for Sr

{Cl}_{2}

{La}^{2 +}

, a system exhibiting the dynamic Jahn-Teller effect. Observed temperature and sample dependences are consequences of a rapid direct relaxation process between the vibronic components of the

{}^{2}E

ground state. This interpretation is consistent with similar effects seen for

{Cu}^{2 +}

{Sc}^{2 +}

, and

{Eu}^{2 +}

in cubic crystals.
