  By employing the multilevel algorithm in numerical Monte Carlo simulations,
we evaluate the static potential in four dimensional SU(2) lattice gauge theory
with no dynamical fermions, for static sources in the j=1/2,1,3/2
representations. We find data supporting the Casimir scaling hypothesis. With
the same technique we show that the ratio of the logarithm of Wilson loops in
the j=2 and j=1/2 representations, as a function of the area of the loops, also
satisfies Casimir scaling.
