The 3d - 1s two-photon decay in hafnium in the resonance region

(Part of abstract) Nuclear electron-capture decay of ^(179)Ta was used to generate hafnium atoms in the K^(-1) state. Two planar germanium detectors were used for the detection of emission of photon pairs. The continuous spectrum due to the 3d-> 1s two-photon decay was fitted by the results of a modified theory of two-photon decay in H-like systems of Florescu et al.
