  In this paper we study the focusing cubic wave equation in 1+5 dimensions
with radial initial data as well as the one-equivariant wave maps equation in
1+3 dimensions with the model target manifolds $\mathbb{S}^3$ and
$\mathbb{H}^3$. In both cases the scaling for the equation leaves the
$\dot{H}^{\frac{3}{2}} \times \dot{H}^{\frac{1}{2}}$-norm of the solution
invariant, which means that the equation is super-critical with respect to the
conserved energy. Here we prove a conditional scattering result: If the
critical norm of the solution stays bounded on its maximal time of existence,
then the solution is global in time and scatters to free waves both forwards
and backwards in infinite time. The methods in this paper also apply to all
supercritical power-type nonlinearities for both the focusing and defocusing
radial semi-linear equation in 1+5 dimensions, yielding analogous results.
