Description
By studying the neutron skin thickness across the Sn isotopic chain, one can gain a rich insight into the slope of the density dependence of the symmetry energy. A novel method using the total neutron-removal cross section (𝜎𝛥N) has been shown to be highly sensitive to the slope, with a 1% change in 𝜎𝛥N corresponding to a variation of L=±5 MeV. Experiments that have been performed at GSI at 400<E/A (MeV/nuc)<900 with
120,124,128,132,134Sn projectiles on p and 12C
targets will be discussed in this presentation.
