Abstract
Bubble translations carried out at small drive fields show a dependence of the minimum gradient amplitude needed for a motion as a function of its duration. The phenomenon can be described in terms of an activated process, with an activation energy inversely proportional to the gradient field. This law is interpreted by using a model where the motion is accomplished through bubble surface variations.Keywords
