“…As shown in Refs. [33][34][35] , the neutron-skin effect, quadruple and octupole deformations are needed to be taken into account to explain the measured differences, which supports the existence of neutron-skin structure and nuclear deformation in the two isobar nuclei [36][37][38][39]. In other words, their nucleon density distributions should be described by a deformed Woods-Saxon (WS) form with some proper deformation parameters considering these effects.…”

Isobar collisions which were thought with a same background and different magnetic fields provide an opportunity to verify the chiral magnetic effect (CME) in relativistic heavy-ion collisions. However, the first result from the RHIC-STAR isobar experiment did not observed the CME signal, but discovered that the backgrounds are different between 96 44 Ru + 96 44 Ru and 96 40 Zr + 96 40 Zr collisions. We test eighteen cases of Woods-Saxon parameter settings resulted from different nuclear deformation or nuclear structure effects using a mutiphase transport model. We find out that seven cases can reasonably reproduce three reference ratios measured by the STAR experiment. With considering both the halo-type neutron skin structure and CME-like charge separation, we demonstrate that it is difficult for the CME observables (∆δ, ∆δ ratio, ∆γ and ∆γ/v 2 ratio) to distinguish the presence or absence of the CME, if the CME strength is weak in isobar collisions. It is because the final state interactions significantly weaken the initial CME signal, resulting in non-linear sensitivities of the CME observables to the CME strength. Therefore, more sensitive observables are required to search for the possible small CME signal in isobar collisions.

“…Examples include the impact on the strength distribution of Gamow-Teller resonances affecting the weak processes occurring alongside the rprocess in supernovae [13]. A detailed analysis of the role of tensor interaction in weak processes taking place in stars undergoing a gravitational collapse is also given in [14,15].…”

The influence of the tensor interaction of nucleons on the characteristics of neutron-rich silicon and nickel isotopes was studied in this work. Tensor forces are taken into account within the framework of the Hartree-Fock approach with the Skyrme interaction. It is shown that the addition of tensor component of interaction improves the description of the splitting between different single-particle states and leads to a decrease in nucleon-nucleon pairing correlations in silicon and nickel nuclei. Special attention was given to the role of isovector tensor forces relevant for interaction of like nucleons.
