| Abstract: | A new method using low energy π+ elastic scattering is employed to determine the proton matter distribution of a nucleus relative to an adjacent nucleus differing by one proton. The difference in the rms charge radii of 12C and 11B was determined to be 0.072 ± 0.021 fm with π+ beam energies of 38.6 and 47.7 MeV. |
