Updated values and corresponding uncertainties of isovector giant dipole resonance (IVGDR or GDR) model parameters are presented that are obtained by the least-squares fitting of theoretical photoabsorption cross sections to experimental data. The theoretical photoabsorption cross section is taken as a sum of the components corresponding to excitation of the GDR and quasideuteron contribution to the experimental photoabsorption cross section. The present compilation covers experimental data as of January 2010.
► Experimental
σ
(
γ
, abs) or a sum of partial cross sections are taken as input to the fitting. ► Data include contributions from photoproton reactions. ► Standard (SLO) or modified (SMLO) Lorentzian approaches are used for formulating GDR models. ► Spherical or axially deformed nuclear shapes are used in GDR least-squares fit. ► Values and uncertainties of the SLO and SMLO GDR model parameters are tabulated.
