Elastic scattering of 6He and its analysis within a four-body eikonal model

We have measured the elastic scattering of a 6He secondary beam on a 12C target at 41.6 MeV/u. The secondary beam was produced by fragmentation with SISSI, and transported to SPEG. The combined use of SISSI and SPEG allows very good quality data to be obtained in terms of energy and angular resoluti...

Description
Summary:We have measured the elastic scattering of a 6He secondary beam on a 12C target at 41.6 MeV/u. The secondary beam was produced by fragmentation with SISSI, and transported to SPEG. The combined use of SISSI and SPEG allows very good quality data to be obtained in terms of energy and angular resolution. The cross section is analysed within a 4-body (α+n+n+ 12C) eikonal scattering model which is completely parameter-free. Very good agreement with the data is found.
