What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.

It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.

If you're a ResearchGate member, you can follow this page to keep up with this author's work.

If you are this author, and you don't want us to display this page anymore, please let us know.

Electromagnetic transitions within nuclei reflect specific aspects of nuclear structure. This is particularly true for metastable excited states, or isomers, like 178Hfm2 (T1/2=31 years, excitation energy 2446 keV). The interaction of external radiation with isomers can be used to study atomic and nuclear properties and, perhaps, to induce a releas...

Over the past six years, a number of reports have been made claiming experimental demonstrations that externally-produced photons near 10 keV could trigger a depopulation (with concurrent gamma emission and energy release) from the 31-year isomer ^178m2Hf. The most compelling of these claims resulted from studies performed at synchrotrons, most not...

... It will be interesting to repeat the photo-excitation experiment with a high-brilliance LCB γ beam. Other de-excitation studies addressed the 31-year J π ; K = 16 + ; 16 isomer in 178 Hf [37][38][39]. The results are contoversial, since the latter two experiments [38,39] do not confirm the claim of the first experiment that the resonant absorption of an X-ray photon with the energy of the order of 40 keV can induce the prompt release of the 2.446 MeV stored by the isomer [37]. ...
