Two-deuteron correlation functions in ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$${+}^{27}$Al collisions at E/A=75 MeV

Both two-deuteron and two-proton correlation functions, at small relative momenta, have been measured for ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$${+}^{27}$Al collisions at E/A=75 MeV. Data are compared to the predictions of a microscopic transport model which incorporates deuteron production and Coulomb interactions. The results indicate that deuterons are emitted over a shorter time span than protons.
