Description

The deformation (quadruple, triaxial, octupole, etc.) and substructure (clustering) of atomic nuclei are paramount to developing a complete understanding of nuclear structure. Various cluster structures emerge depending on the excitation energy, the number and kinds of core clusters, and excess neutrons. In low-lying states, clusters are generally tightly bound; however, the correlation between clusters and the actual way of cluster formation is not fully charted. We will present results from our ongoing feasibility studies using different measures for nuclear deformation and clustering with the EPIC detector at the Electron-Ion Collider. Simulation results obtained with the BeAGLE model [1] will be presented and discussed for e+Be, e+C, e+O, e+Pb, and e+U collisions. Our results suggest that measurements with the EIC's mid- and forward-rapidity ePIC detectors could give new insights into nuclear deformation and alpha clustering in atomic nuclei.
