Abstract: (Elsevier)
We calculate the single nucleon intermediate state contribution to the electric dipole moment of the neutron induced by the vacuum angle θ. We find the value | D n | = 1.1 × 10 −15 | θ | e cm, which dominates over other possible contributions. Current experimental bound on D n yields | θ | < 4 × 10 −10 .- N: FORM FACTOR
