Astrophysical relevance of the low-energy dipole strength of 206Pb

Astrophysical relevance of the low-energy dipole strength of 206Pb

The dipole strength of 206Pb was studied below the neutron separation energy using photon scattering experiments at the HIGS facility. Utilizing the technique of nuclear resonance fluorescence with 100% linearly-polarized photon beams, the spins, parities, branching ratios and decay widths of excite...
