One of the objectives of the s393 experiment is to study unbound nuclei on the neutron-rich side of the nuclei chart surviving a (p,2p) knockout reaction. After the quasi-free scattering in the target, the unbound nuclei lose one neutron which will reach the Large Area Neutron Detector, LAND, the remaining isotope bent by ALADIN is selected in the fragment detector branch (GFI-TFW). Together this allows for a reconstruction of the invariant mass. Further, it's possible to use the gamma detector (Crystall Ball) to do gamma-coincidence measurement.
The analysis is in a very preliminary state, I will present the available statistics from the S393 experiment for different nuclei beyond the dripline. I will report on the current situation and future expectations.
