Charge-changing cross sections and charge radii of B, C, and N isotopes

The charge-changing cross sections σ _cc of ¹⁰⁻¹³ B, ¹¹⁻¹³ C, and 12,13 N nuclides on multiple targets were measured at the energy of about 170 MeV/nucleon. The point-proton radii of these nuclides were determined by comparing the experimental σ _cc with the Glauber model calculation considering the charged-particle evaporation effect. For 12,13 B, the present results are consistent with the existing experimental data deduced by different methods.
