Search for narrow nucleon resonances below pion threshold in the H(e, e'pi+)X and 2H(e, e'p)X reactions
In two series of high-resolution coincidence experiments at the three-spectrometer facility at MAMI, the H(e, epi+)X and 2H(e, ep)X reactions were studied to search for narrow nucleon resonances below pion threshold. The missing-mass resolution was 0.6-1.6 MeV/c2 full width at half maximum in the proton experiment and 0.9-1.3 MeV/c2 in the deuteron experiment. The experiments covered the missing-mass region from the neutron mass up to about 1050 and 1100 MeV/c2, respectively. None of our measurements showed a signal for narrow resonances to a level of down to 10-4 with respect to the neutron peak in the missing-mass spectra.
