Deblurring for nuclei: 3D characteristics of heavy-ion collisions

NUCLEAR REACTIONS ¹²⁴Sn(¹³²Sn, X), E=270 MeV/nucleon; analyzed RIKEN data (2021Jh01: Phys. Lett. B813, 136016) for triple differential distributions of neutrons and protons using the Boltzmann-Uhlenbeck-Uehling (pBUU) simulations. ²⁰⁸Pb(²⁰⁸Pb, X), E=250 MeV/nucleon; analyzed ratio of neutron to proton yields at midrapidity, in the direction perpendicular to the reaction plane, as a function of transverse momentum. Richardson-Lucy deblurring methods, such as in optics, used to correct for degradation in observable such as final-state characteristics of heavy-ion collisions.
