Research Description

My research covers both nuclear structure and nuclear reactions. In a study of the many body effects in nuclei, we have determined how the proton correlations in Ca nuclei change as the number of neutrons is increased. This work involved a dispersive-optical-model analysis of nucleon-elastic-scattering data and information on the bound single-particle states. A new experimental program has been initiated to determine how neutron correlations change. Correlations between fragments have been measured for three-body decays of ⁶Be and excited states of ¹⁰C nuclei. A ¹⁰C excited state was found with a exotic two-proton decay branch processing a strong diproton character.
