Besides the single-particle nature of the excited nuclear states from the PDR region, different properties of the low-energy dipole strength emerge from the analysis of inelastic photon-, proton- and alpha-scattering spectral distributions and branching ratios, from which the fine structure of the low-energy dipole strength and the role of quasicontinuum coupling can be probed. Experimentally, the determination of the dipole strength distribution and the associated photoabsorption cross section requires knowledge of the intensity distribution of the ground state transitions and their branching ratios.
