摘要：

A measurement of DELTA-sigma-L (np), the difference between neutron-proton total cross sections in pure longitudinal spin states, is described. Data were taken for five energies between 500 and 800 MeV, with statistical errors of almost-equal-to 1.5 mb and an estimated normalization error of 6%. The data, combined with other results, show some evidence for an elastic I = 0 spin-singlet resonance with mass approximately 2213 MeV and width approximately 74 MeV, or a coupled-triplet resonance with similar mass and width.
