E89-042 CLAS Experiment
- Spokespersons
- V. D. Burkert, R. Minehart
- Year
- 2003
- Abstract
- The polarized longitudinal-transverse structure function has been measured in the Delta resonance region. For the first time a complete angular distribution was measured, permitting the separation of different non-resonant amplitudes using a partial wave analysis.
