Study of the momentum correlation of nucleons in 4496Ru + 4496Ru and 4096Zr + 4096Zr collisions at sNN=7.7 and 200 GeV from a multiphase transport model
By using A MultiPhase Transport (AMPT) model in the string melting scenario, the influences of nuclear structure on the momentum correlation functions between nucleons in the isobaric collisions of 4496Ru + 4496Ru and 4096Zr + 4096Zr at sNN=7.7 and 200 GeV were investigated. The results, including the centrality dependence of the correlation functions, were compared across different parameterizations of the Woods-Saxon distribution corresponding to varying deformation configurations in the simulation. A maximum difference of 4% was observed between the isobaric systems for the proton-proton correlation functions when including quadrupole (β2) and octupole (β3) deformation. In peripheral collisions, the Ru + Ru and Zr + Zr systems exhibited maximum differences of 4% and 5%, respectively, when comparing different parametrization cases. Furthermore, neutron-proton correlation has been studied, showing a sensitivity to nuclear structure comparable to proton-proton correlations. Our results indicate that in peripheral collisions, there may be measurable effects of momentum correlation functions from nuclear deformation and neutron skin in high-precision experimental data, whereas in central collisions, both effects may show negligible influence on momentum correlation functions.

Dynamics of light nuclei produced in the massive transfer reactions
Within the framework of the dinuclear system (DNS) model by implementing the cluster transfer into the dissipation process, we systematically investigated the energy spectra and the angular distribution of the preequilibrium clusters (n, p, d, t, 3He, α, 6,7Li, 8,9Be) in the massive transfer reactions of 12C+209Bi, 14N+159Tb, 14N+169Tm, 14N+181Ta, 14N+197Au, 14N+209Bi, 58,64,72Ni+198Pt near the Coulomb barrier energies. It was found that the neutron emission is the most probable in comparison with the charged particles, and the α yields are comparable to the hydrogen isotopes in magnitude. Preequilibrium clusters are mainly produced from projectile-like and target-like fragments during the evolution of the dinuclear system. The kinetic energy spectra manifest a Boltzmann distribution, and the Coulomb potential influences the structure. The pre-equilibrium clusters follow the angular distribution of the multinucleon transfer fragments.

New laser spectroscopy measurements challenge modern nuclear theories
When discussing atomic nuclei, deformation is one of the most common topics. However, when we connect the concept of shape with high-precision experimental measurements, sometimes the explanation may not be as simple as we think. A recent measurement of nuclear charge radii (Phys. Rev. Lett. 134, 182501 (2025)) challenges current nuclear ab initio models.
