Impact-parameter-selected two-proton intensity interferometry forAr36+45Sc atE/A=80 MeV

The momentum dependence of the two-proton correlation function is studied for central and peripheral ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}$ ${+}^{45}$Sc collisions at E/A=80 MeV. Calculations with the Boltzmann-Uehling-Uhlenbeck transport theory reproduce well the measured momentum dependence of the correlation functions for central collisions, but underpredict the momentum dependence for peripheral collisions.
