Binding energy shifts from heavy-ion experiments in a nuclear statistical equilibrium model

Chemical constants extracted from $$^{124}$$ Xe+ Sn collisions at 32 AMeV are compared to the predictions of an extended nuclear statistical equilibrium model including mean-field interactions and in-medium binding energy shifts for light ( $$Z\le 2$$ ) clusters. The ion species density dependence modification is directly experimental data. We show that shift increases with mass cluster medium, we provide a simple linear fit future use in astrophysical simulations framework CompOSE data base. resulting fractions computed representative thermodynamic conditions relevant supernova neutron star mergers. A comparison results similar analysis same performed relativistic shows good agreement low density, but significant discrepancies close Mott dissolution clusters dense medium.
