The irradiation of an enriched sample of /sup 180/Ta/sup m/ with bremsstrahlung from a linear accelerator having an end point energy of 6 MeV has excited a strong channel for the reaction /sup 180/Ta/sup m/(..gamma..,..gamma..')/sup 180/Ta, which requires a total spin change of 8(h/2..pi..). An integrated cross section of 4.8 x 10/sup -25/ cm/sup 2/ keV has been found. This is a large value exceeding by 2 orders of magnitude known cross sections for (..gamma..,..gamma..') reactions producing isomers of other species.
