Abstract
For certain artinian modules over group rings, we obtain the Baer decomposition, that is, a direct decomposition into two summands such that all chief factors of the first summand are ${\mathcal X}$-central and all chief factors of the second summand are ${\mathcal X}$-eccentric, for some formation $\mathcal X$ of finite groups.
