Visualizing differences in nuclear structure

The horizontal axis represents the proton scattering angle and the vertical axis represents the ease with which protons are scattered. C-type and S-type are theoretical values assuming cluster and shell structure, respectively. Expt. is existing data. Credit: Wataru Horiuchi, OMU

Helium usually has two protons and two neutrons strongly bound to each other, often forming a substructure within the nucleus. A nucleus composed of several such substructures is called a cluster structure. In the…
