In this paper, we show the stability of Gustafson, Weidmann, Kato, Wolf, Schechter and Browder essential spectrum of bounded linear operators on Banach spaces which remain invariant under additive perturbations
belonging to a broad classes of operators $U$ such <that> $\gamma(U^m)<1$ where $\gamma(.)$ is a measure of
noncompactness.
