Experimental determination of the neutron detection efficiency for the testing of the results of a measurement of the magnetic neutron form factor at ELSA

Description

A pion production experiment with almost real photons on 1H has been carried out at the electron stretcher accelerator ELSA to determine the neutron detection efficiency of the large solid angle acceptance nonmagnetic ELAN Time-of-Flight spectrometer. The source of unknown discrepancy between the neutron magnetic form factor values measured at ELSA and MAMI could no longer be attributed to a wrong detection efficiency of the ELSA data. A GEANT Monte Carlo calculation has been adapted to determine the detection efficiency for the ToF spectrometer. The result of this simulation is ηGeant=3.1%±0.2% in very good agreement with the experimental value of ηExp=3.2%±0.2%. (orig.)
