Cole Pruitt, Lawrence Livermore National Laboratory, will be speaking.

The presentation is titled "Neutron Skins from Neutron Scattering: How Well Do We Understand Asymmetry-Dependence?"

The abstract is as follows: Many fundamental questions of nuclear physics (where is the neutron dripline? where and how does the r-process occur?) hinge on how nuclear behavior changes as a function of asymmetry. Neutron elastic and inelastic scattering measurements on stable targets help constrain reaction-model asymmetry-dependence by providing information complementary to that from facilities like FRIB. This seminar will detail our recent campaign of isotopically-resolved neutron total cross section measurements on 16,18O, 58,64Ni, 112,124Sn at the Los Alamos Neutron Science Center (LANSCE) and our implementation of the Dispersive Optical Model (DOM), which connects these experimental cross sections to nuclear structure. From our DOM analysis, we make predictions for the neutron skin thicknesses of several cornerstone nuclei, then identify some major hurdles for the next generation of optical models needed to navigate the FRIB era.
