Maximal acceleration effects in Kerr space

We consider a model in which accelerated particles experience line-elements with maximal acceleration corrections that are introduced by means of succ essive approximations. It is shown that approximations higher than the firs t need not be considered. The method is then applied to the Kerr metric. Th e effective field experienced by accelerated test particles contains correc tions that vanish in the limit h --> 0, but otherwise affect the behaviour of matter greatly. The corrections generate potential barriers that are ext ernal to the horizon and are impervious to classical particles. (C) 2001 El sevier Science B.V. All rights reserved.
