The total cross section of slow neutrons on gaseous orthodeuterium has been measured near 22 K and at pressures ranging from 145 to 300 Torr. The results give rise to a set of values for the neutron-deuteron scattering lengths that are in significant disagreement with the latest liquid mirror measurements. The relationship between the scattering lengths was found to be: (2a4+a2)2+(54)(a4-a2)2=(2.313±0.003)×10-24 cm2. NUCLEAR REACTIONS H2(n, n); E=4.2 meV; orthodeuterium; measured total neutron cross section; deduced relationship between a2 and a4.
