Accelerated Emission of Gamma Rays from the 31-yr Isomer of ¹⁷⁸Hf Induced by X-Ray Irradiation

NUCLEAR REACTIONS ^178mHf(X-ray, γ), E=70, 90 keV bremsstralung; measured Eγ, Iγ(t); deduced accelerated decay, resonant x-ray absorption σ.

RADIOACTIVITY ^178mHf(IT); measured Eγ, Iγ(t) with and without x-ray irradiation; deduced accelerated decay, resonant x-ray absorption σ.
