The so far precisely measured charge radii difference data within their experimental uncertainty ranges in the ³⁴Ar-³⁴S, ³⁶Ca-³⁶S, ³⁸Ca-³⁸Ar, and ⁵⁴Ni-⁵⁴Fe mirror pairs are used to ascertain an upper limit for the slope parameter of the nuclear symmetry energy <em>L</em> ≈ 100 MeV. This limiting value of L is found to be consistent with the upper bound of the NICER PSR J0740+6620 constraint at 1σ level for the radius R_1.4 of 1.4M neutron stars. The lower bound of the NICER R_1.4 data constrains the lower limit of <em>L</em> to ≈70 MeV. Within the range for <em>L</em> = 70–100 MeV the tidal deformability <em>Lambda</em>^1.4 constraint, which is extracted from the GW170817 event at 2σ level, and the recent PREX-2 and CREX data on the neutron skin thickness are discussed.8 p.application/pdfeng(c) American Physical Society, 2023Estels de neutronsPropietats de la matèriaFísica nuclearNeutron starsProperties of matterNuclear physicsinfo:eu-repo/semantics/article7448382024-09-27info:eu-repo/semantics/openAccess
