Dynamical treatment of quenching-factors (Ham-factors) for the linear E-e Jahn-teller problem

The quenching factors for the linear E-e Jahn-Teller system are calculated by use of the exponential transformation method. In the extremal coupling cases the results are identical with those of Ham 1] and others 2]. For intermediate interactions, however, the factors p and q do not exhibit a monotonic overall decrease with increasing coupling strength, as suggested by Ham. Instead, both p and q have a minimum. In addition, p crosses the zero axis for λ ≌ 0.66.
