Description
In T. Tachibana et al., Phys. Rev. C 112 (2025) 065806, the equation of state of spin-polarized nuclear matter was studied and the spin slope parameter of the corresponding spin-symmetry energy was discussed, which plays an important role in characterizing spin-dependent properties of nuclear systems. To explore a possible experimental probe for constraining the spin slope parameter, we investigate a new type of “skin thickness” in high-spin isomers. In analogy with the well-known linear correlation between the neutron skin thickness and the slope parameter in nuclear matter, we examine the correlation between the “spin skin thickness” of the high-spin isomer of 52Fe and the spin slope parameter. For this purpose, two possible definitions of the spin skin thickness are introduced and analyzed within the framework of the relativistic density functional theory.
