The [ital K][sup [pi]]=8[sup [minus]] isomer at 1147.4 keV in [sup 178]Hf was populated in a Coulomb excitation experiment with [sup 130]Te ions. The measured cross section for this isomer was 2.7[plus minus][sub 1.4][sup 1.9], 4.3[plus minus][sub 2.0][sup 3.4], and 7.5[plus minus][sub 3.2][sup 6.1] mb for three beam energies below the Coulomb barrier, namely 560, 590, and 620 MeV. If one assumes that the projection of the total angular momentum on the symmetry axis, [ital K], is only an approximate quantum number, the population of this isomer can be reproduced via direct [ital E]3 excitations of odd spin members of the isomeric band from the ground state band.
