[Prex] Neutron skin thickness for Pb from total cross sections of neutron scattering

[Jay Benesch]

Stupid outlook won't let me send to prex  or edit the contact name above.   Ca48 value also in agreement with CREX, albeit larger so the tension we saw isn't as great.

Neutron skin thickness for    Pb from total cross sections of neutron scattering at 14.137 MeV and neutron skin thickness for    Ca, O, N, C isotopes from reaction and interaction cross sections

    Foster {\it et al.} measured total neutron cross sections     of n+   Pb scattering at    ~MeV. We tested the Kyushu (chira)l  -matrix folding model for reaction cross sections     on p+   Pb scattering in $20 \lsim E_{\rm lab} \lsim 180$MeV and found that our folding model is reliable. As for    C+   C scattering, we tested the Kyushu  -matrix folding model and found that the folding model is reliable for     in $30 \lsim E_{\rm lab} \lsim 100$~MeV/u and $250 \lsim E_{\rm lab} \lsim 400$MeV/u. Ozawa {\it et al.} accumulated the measured values of interaction cross sections     and the extracted matter radii     from    He to    Mg. Bagchi {\it et al.} determined proton radii     for    N by measuring the charge-changing (CC) cross sections, and found a signal of    N being a halo nucleus. Kanungo {\it et al.} measured the CC cross sections and extracted     for    C. Kaur {\it et al.} made a similar measurement and determined     for    O. Our 1st aim is to extract neutron skin thickness      from the     of n+   Pb scattering at    MeV. Our 2nd aim is to test the Kyushu  -matrix folding model for    He+   Pb scattering in $30 \lsim E_{\rm lab} \lsim 180$MeV. 0ur 3rd aim is to find stable nuclei having nuclei having large    . We extract     ~fm from the    . We find that    ~fm for    N and    ~fm for    O. The value     ~fm agrees with     .
