Isotopic Dependence of Giant Monopole Resonance (GMR) in the ^106-116Cd isotopes and the asymmetry term in nuclear incompressibility
Abstract
The asymmetry term associated with the neutron excess, Kτ, plays a very important role in the Equation of State (EOS) for neutron matter. The GMR studied over a series of isotopes provides a direct way to measure this term. We have measured GMR strength distributions in even A, ^106-116Cd isotopes in an experiment performed at RCNP, Osaka University, Japan. Measurements were taken at forward angles, including 0 , using a 400 MeV α beam. The results affirm the conclusions of a recent experiment with the Sn isotopes. The constraints put by values of Kτ and K∞, obtained from this experiment on the effective interaction currently in use in nuclear structure and EOS calculations, will be discussed. ---
