We consider a semilinear elliptic problem in an annulus of R^N, with N>1.Recent results ensure that there exists a sequence p_k of exponents of thenonlinear term at which a nonradial bifurcation from the radial solutionoccurs. Exploiting the properties of O(N-1)-invariant spherical harmonics, weintroduce two suitable cones K^1 and $K^2$ of O(N-1)-invariant functions thatallow to separate the branches of bifurcating solutions from the others,getting the unboundedness of these branches.
