A new set of picosecond lifetime measurements in neutron-rich yttrium gives nuclear physicists a sharper test of how shape coexistence and configuration changes develop near neutron number 60.

Calculations predict a sign-reversed polarization transfer near 151 MeV, while the proposed EPR-like test is limited by the energy of the second scattering.

A carbon-target photon experiment found a lower-tail excess in low-momentum η′→γγ events and inferred a possible 57.5 MeV/c² mass reduction at normal nuclear density, with an uncertainty of +5.7/−27.8 MeV/c².

The computational comparison found different modeled rare-earth abundance patterns across six nuclear level-density models and three simulated outflow scenarios, with the strongest contrast in the cold case.

An analysis of model errors found lower out-of-fold and blind-test RMSE after applying ARCUS to WS* and HFB-25. Performance varied across regions, and a calcium-52 case showed that local residual patterns do not guarantee an accurate correction.

A computational study of helium-8 finds a negative energy curvature and several interaction-specific diagnostics that the authors interpret as evidence for a cooperative two-pair neutron structure.

A new arXiv preprint examines how two conventions for describing relativistic fluids affect transport coefficients. In its Boltzmann nucleon-gas model, the Landau–Lifshitz conductivity is lower than the Eckart value, while the calculated sound attenuation coefficient is identical in both descriptions.

A theoretical preprint connects a two-scale nucleon picture with dense-matter modeling and neutron-star constraints, reporting possible high-density sound-speed and transition behavior without selecting a unique outcome.
