Neutron pairing gaps in calcium isotopes are insensitive to variations in third-order chiral interactions, indicating that nuclear superfluidity requires improved many-body modeling or higher-order terms.
Application of the CBS rotor model to rare-earth even-even nuclei produces calculated ground-state band energies, B(E2) transition rates, and beta-band excitations that are compared with experimental data and used to predict unmeasured observables.
Realistic nuclear cluster wave functions show broader spatial distributions and non-Gaussian structures than Gaussian ansätze with matching rms radius, suggesting a mechanism to address underestimation of A=4 cluster production.
Review highlighting ab initio calculations for heavy nuclei and dark matter-nucleus scattering to reduce nuclear uncertainties.
