Photoexcitation of the long-lived isomers {sup 123}Te{sup {ital m}}, {ital T}{sub 1/2}=119.7 d, and {sup 125}Te{sup {ital m}}, {ital T}{sub 1/2}=58 d, was produced with bremsstrahlung from the superconducting Darmstadt linear accelerator. The excitation function for the reaction {sup 123}Te({gamma},{gamma}{prime}){sup 123}Te{sup {ital m}} was measured between 2 and 6 MeV. It indicated that the isomer was populated by resonant absorption through isolated intermediate states having integrated cross sections in excess of 10{sup {minus}26} cm{sup 2} keV, i.e., values about 100 times larger than most ({gamma},{gamma}{prime}) activation reactions reported previously. An excitation function was also obtained for the reaction {sup 125}Te({gamma},{gamma}{prime}){sup 125}Te{sup {ital m}} in this energy range.
