| dc.description.abstract | Two new formulas for the (−2) moment of the photoabsorption cross section, σ−2, have been determined, respectively, from the 1988 photoneutron evaluation of Dietrich and Berman and a mass-dependent symmetry energy coefficient, asym(A). The data for A 50 follow, with a RMS deviation of 6%, the power law σ−2 = 2.4A5/3 μb/MeV, which is in agreement with Migdal’s calculation of σ−2 = 2.25A5/3 μb/MeV based on the hydrodynamic model and the σ−2 sum rule. The additional inclusion of asym(A) provides a deeper insight into the nuclear polarization of A 10 nuclei. | en_US |
