摘要：

The photon energy spectrum from the reaction π- + d → 2n + γ at zero energy has been measured by pair spectrometer using acoustic spark chambers to locate the pair electron tracks. From the shape of the spectrum the neutron-neutron scattering length was determined to be ann = 13.1-3.4+2.4 fm. The probability of existence of a bound state of two neutrons was calculated to be less than 5 × 10-9. © 1968.
