Abstract
A search has been made for coincident, equal-energy, 180° correlatedγ-rays from252Cf fission decay. Theseγ-rays may arise if new neutral particles are produced in fission, and if they decay byγ-emission. The fraction of fissions which give rise to particles at rest with masses between 1.4 and 2.0 MeV, which then decay into twoγ-rays in a time ≲ 10−19s, is less than 8 × 10−7 at the 95% confidence level.
