Abstract: Let $ du$ be a smooth positive measure carried by a smooth compact hypersurface $ S$ that is strictly convex and without boundary in $ {R^n}(n \geqslant 2)$. Assume that both $ S$ and $ du$ are symmetric about the origin. If $ \hat du$ denotes the Fourier transform of $ du$ then we show that the null set of $ \hat du$ is a disjoint union of a compact set and countably many hypersurfaces that are all diffeomorphic to the unit sphere $ {S^{n - 1}}$.
