| Abstract: | Non-equilibrium populations of defects, produced by plastic deformation of Ni, were used to study temperature dependence of
the capture cross-section for positrons. A weak positive temperature coefficient was found in material of 99.8% purity but
no temperature dependence in 99.99% purity. |
