First Extraction of the Matter Radius of 132Sn via Proton Elastic Scattering at 200 MeV/Nucleon
Abstract The angular distribution of the differential cross sections for proton elastic scattering from $^{132}$Sn at 196–210 MeV/nucleon was successfully measured over a momentum transfer range of 0.80–2.1 fm$^{-1}$. Using a relativistic impulse approximation, the root-mean-square matter radius of $^{132}$Sn was extracted as $4.758^{+0.023}_{-0.024}$ fm, which was compared with the state-of-the-art ab initio calculations. Combined with the charge radius measured at ISOLDE, there are no theoretical calculations consistent with both matter and charge radii within the experimental errors.
