Positron annihilation spectroscopy and transmission electron microscopy reveal new insights into radiation damage processes

Caption

A combination of positron annihilation spectroscopy and transmission electron microscopy reveals new insights into how damage is formed in irradiated materials, suggesting a mechanism in which large holes in the material absorb atoms in interstitial positions in the lattice and shrink, but leave behind more positions that are missing atoms.
