  We investigated the 238U(d,p) reaction as a surrogate for the n + 238U
reaction. For this purpose we measured for the first time the gamma-decay and
fission probabilities of 239U* simultaneously and compared them to the
corresponding neutron-induced data. We present the details of the procedure to
infer the decay probabilities, as well as a thorough uncertainty analysis,
including parameter correlations. Calculations based on the
continuum-discretized coupled-channels and distorted-wave Born approximations
were used to correct our data from detected protons originating from elastic
and inelastic deuteron breakup. In the region where the fission and gamma-decay
probabilities compete, the corrected fission probability is in agreement with
neutron-induced data, whereas the gamma-decay probability is much higher than
the neutron-induced data. The performed statistical-model calculations are not
able to explain these results.
