Constraining the parameters of the nuclear Equation of State (EoS) is one of the central issues in nuclear physics, especially since the slope parameter L has not yet been constrained well experimentally. It has been identified that a precise determination of the neutron-removal cross section in neutron-rich nuclei, which correlates with the neutron-skin thickness, would provide a more precise constraint on L. To this end, an experiment was performed at the R3B setup at GSI as a part of the FAIR Phase-0 program. The reactions are studied in inverse kinematics with neutron-rich tin isotopes in the mass range A=124–134 on carbon targets of different thicknesses. In this communication the charge-changing and charge-exchange analysis of 124Sn+12C at 900 MeV/u is presented.
The project was supported by the BMBF via Project No. 05P21RDFN2, the Helmholtz Research Academy Hessen for FAIR and the GSI-TU Darmstadt cooperation agreement.
