Angular dependence in proton-proton correlation functions in central40Ca + 40Ca and48Ca + 48Ca reactions
The angular dependence of proton-proton correlation functions is studied in central ${}^{\text{40}}\text{Ca}+{\phantom{\rule{0.16em}{0ex}}}^{\text{40}}\text{Ca}$ and ${}^{\text{48}}\text{Ca}+{\phantom{\rule{0.16em}{0ex}}}^{\text{48}}\text{Ca}$ nuclear reactions at $E/A=80$ MeV. Measurements were performed with the High Resolution Array (HiRA) complemented by the 4$\ensuremath{\pi}$ Array at the National Superconducting Cyclotron Laboratory. A striking angular dependence in the laboratory frame is found within …
