Separation of protons and neutrons with the CBELSA/TAPS experiment — •Nadia Reinartz for the CBELSA/TAPS collaboration — HISKP, Uni Bonn

The ELSA accelerator can provide a polarised electron beam that together with the polarised target of the CBELSA/TAPS experiment makes it possible to determine single or double polarisation observables for various final states. The Crystal Barrel (CB) calorimeter in combination with the MiniTAPS calorimeter in forward direction, allows measurements in a full 4 π coverage. In the past it was difficult to efficiently measure reactions with a neutron in the final state.

In the last years the CBELSA/TAPS experiment in Bonn has been improved in order to significantly boost the efficiency for detecting neutrons in the main calorimeter. The data taken after the upgrade was used to determine methods for identifying protons and neutrons with beam energies between 600 MeV and 3200 MeV. In this talk an overview about those results is presented.
