Measurement of the imaginary part of the I=1 S-wave scattering length
The survival time spectrum of slow antineutrons produced in a liquid-hydrogen target has been measured. From these data the imaginary part of the I=1 spin-averaged S-wave antineutron proton scattering length has been deduced to be Ima1=-0.83±0.07 fm. The result lies within the range of values calculated from current potential models. In addition, by combining a1 with the antiproton-proton scattering length deduced from antiprotonic atoms, the imaginary part of the I=0 spin-averaged N¯N scattering length was calculated to be Ima0=-1.07±0.16 fm.
