摘要：

We consider examples of the tunneling of ions in a crystal in which the concept of tunneling from one configuration to another (which we refer to as the tunneling of a cluster of ions) plays a significant role. First we review earlier work on RbCI:Ag with a focus on cluster tunneling. In this system, the Ag+ ion plus the cage of nearest neighbor Cl-ions, tunnels from an off-center, distorted state to an on-center symmetric state. Next we present recent results for KCl.Li+ that suggest that the appropriate cluster for this tunneling system is approximately a Li+ ion plus 3 Cl-ions. © 1991, Taylor & Francis Group, LLC.
