The increase of positron parameters in neutron-irradiated α-iron around 180 K is shown to be due to correlated vacancy migration within displacement cascades. Therefore the recent attempt to use positron annihilation in neutron-irradiated iron as an evidence for interstitial migration at stage III is internally inconsistent and incompatible with well-established experimental results.
