Superheavy nuclei exist solely due to quantum shell effects,
which create a pocket in the potential-energy surface of the nucleus, thus
providing a barrier against spontaneous fission. Determining the height of
the fission barrier and its angular-momentum dependence is important to
quantify the role that microscopic shell corrections play in enhancing and
extending the limits of nuclear stability. In this talk, the first measurement of
a fission barrier in the very heavy nucleus 254No will be presented.
