We report a high-precision determination of the 1S0 neutron-neutron scattering length (ann) using the 2H(π-,ny)n reaction. The value obtained in the present work is -18.50 ± 0.05 (statistical) ± 0.44 (systematic) ± 0.30 (theoretical) fm, which is consistent with the values from previous measurements. Combining our result with previous measurements reduces the total uncertainty in the world average of ann to ±0.4 fm, matching the accuracy to which the charge-symmetric parameter app is determined. © 1998 Elsevier Science B.V.
