Irradiation of Ta with a superconducting linear accelerator has provided data for the characterization of the reaction {sup 180}Ta{sup {ital m}}({gamma},{gamma}{prime}){sup 180}Ta. The depopulation of the isomer {sup 180}Ta{sup {ital m}} via an intermediate state or narrow band of states near 2.8 MeV has been found with an integrated cross section of 1.2{times}10{sup {minus}25} cm{sup 2} keV. This large value exceeds, by nearly an order of magnitude, known cross sections for ({gamma},{gamma}{prime}) reactions producing isomers of other species. Another intermediate state or narrow band is also indicated by the data at an energy 0.6 MeV higher.
