Abstract: In this paper we classify nonorientable topological closed 4-manifolds with fundamental group $ \mathbb{Z}/2$ up to homeomorphism. Our results give a complete list of such manifolds, and show how they can be distinguished by explicit invariants including characteristic numbers and the $ \eta $-invariant associated to a normal $ Pin^c$-structure by the spectral asymmetry of a certain Dirac operator. In contrast to the oriented case, there exist homotopy equivalent nonorientable topological 4-manifolds which are stably homeomorphic (after connected sum with $ {S^2} \times {S^2}$) but not homeomorphic.
