abstract

The neutron skin of $^{208}$Pb has received considerable attention in recent years. A variety of strongly-interacting probes depict a rather consistent picture but pionic probes have not been referred to in this context. We present here neutron-skin values from pionic atoms and from total reaction cross sections of $\pi ^+$ between 0.7 and 2 GeV/c which fit well into the picture. In addition we show that a neutron skin for $^{48}$Ca can be obtained from existing data on pionic atoms and the result agrees with pion scattering experiments and with the scattering of $\alpha $ particles.

  1. Unraveling the neutron skin thickness through jet charge in deep inelastic scattering

    hep-ph 2025-06 conditional novelty 6.0 of 10

    Jet charge distributions in electron-ion collisions are shown to be sensitive to neutron skin thickness, with peripheral collisions suppressing positive jets and enhancing negative jets.

  2. Investigating the possibility of extracting neutron-skin thickness in nuclei by their collisions at intermediate energies

    nucl-th 2024-11 accept novelty 5.0 of 10

    In simulated intermediate-energy tin collisions, the free neutron-to-proton yield ratio is more sensitive to the symmetry potential than to the initial neutron-skin thickness in most kinematics.
