Abstract
The neutron-neutron scattering length is determined from the low energy part of the neutron spectrum of the reaction d→nnγ with pions at rest. Since neutrons are detected in coincidence with the photon, the kinematics is completely determined. We obtain fm, in agreement with a result of a previous experiment based on the analysis the photon spectrum.
