Abstract: Let $f(x)$

be a given positive function in $R^{n+1}$ . In this paper we consider the existence of convex, closed hypersurfaces $X$

so that its Gauss-Kronecker curvature at $x\in X$ is equal to $f(x)$

. This problem has variational structure and the existence of stable solutions has been discussed by Tso (J. Diff. Geom. 34 (1991), 389--410). Using the Mountain Pass Lemma and the Gauss curvature flow we prove the existence of unstable solutions to the problem.
