Abstract: This paper studies symplectic manifolds that admit semi-free circle actions with isolated fixed points. We prove, using results on the Seidel element, that the (small) quantum cohomology of a $ 2n$-dimensional manifold of this type is isomorphic to the (small) quantum cohomology of a product of $ n$ copies of $ \mathbb{P}^1$. This generalizes a result due to Tolman and Weitsman.
