Project: Experimental study of the spin st ructure of the neutron by doubly-polarized total photoabsorption.
- project duration
- 01-JAN-00 – 30-JUN-05
- The spin structure of the nucleon can be studied by the experimental verification of the validity of the value of the Gerasimov-Drell-Hearn sum rule. In such project the total photoabsorption is measured of circularly-polarized real photons on longitudinally-polarized nucleons (in this case a deuterated butanol target is used). The experiments will be performed in the energy range 140-850 MeV at MAMI/Mainz and 500 MeV-3.5 at ELSA/Bonn. Special attention must be paid to the neutron efficiency of the detection systems.
