The level scheme of {sup 238}U has been extended using the so-called unsafe Coulomb excitation technique. One positive-parity band was uncovered for the first time, and its most important features can be related to a double-octupole phonon excitation. This band decays to the known K=0 octupole band via E1 transitions, with strengths much larger than those to the ground-state band. It also decays to the K=1 and 2 octupole bands. Comparisons among the proposed zero-, one-, and two-phonon bands in {sup 238}U and those in {sup 240}Pu shed more light on the recently proposed concept of rotationally aligned octupole phonon condensation.
