Description
Charge symmetry breaking in np elastic scattering at 347 MeV has been measured with high precision. From fits of the measured asymmetry curves over the angular range 53.4 degree ≤θc.m.≤86.9 degree, the difference in the center-of-mass zero-crossing angles of the analyzing powers was determined to be 0.438 degree ±0.054 degree(stat)±0.051 degree(syst). Using the experimentally determined slope of the analyzing power, dA/dθ=(-1.35±0.05)x10-2 deg-1, this is equivalent to ΔA=[59±7(stat)±7(sys)±2(syst)]x10-4. Predictions of nucleon-nucleon interaction models based on meson exchange agree well with this result
