Broken axial symmetry as essential feature for a consistent modelling of various observables in heavy nuclei
2022, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsCitation Excerpt :Radiative widths are important ingredients for the interpretation of nuclear data with photons in one of the channels. There have been many attempts [97] in finding phenomenological expressions for photon strengths and widths to extrapolate from observations made in the valley of stability to neutron capture by exotic nuclei, like those involved in astrophysical processes. It was stated some time ago [6,92], that wide doorway states like the IVGDR have a spreading width depending on the pole energy of the resonance and on the coupling to the underlying narrow states.

2018, Atomic Data and Nuclear Data TablesCitation Excerpt :For medium-mass to heavy nuclei, these effects can be described effectively by an additional broadening of the shape-line. But in some situations, isospin splitting and triaxiality of the nuclear shape have to be considered explicitly in the formulas [29,39–43]. The set of the Lorentzian parameters in the first line (first entry) for each nuclide was determined using, as a rule, the closest experimental data to the total photoabsorption cross sections near GDR and corresponds to minimal least-square deviation in comparison with other entries.
