Abstract: (Elsevier)
The eigenfrequencies of the isovector nuclear vibrations, whose excitation strengths exhaust the classical energy weighted sum rule value, are estimated by making use of various sum rules. The less model dependent forms of the variations of isovector nuclear density and average field under the vibrations are also obtained in the sum rule approach, and used to estimate the isovector effective charges and their momentum transfer dependence, isospin impurity and the correction to the Coulomb energy difference.References(24)
