Abstract

The change in the resistitivity of high-purity α plutonium, due to self-irradiation damage with time of holding in liquid helium, has been measured. A small term, additional to the two terms previously reported, was found. A detailed analysis showed that a good fit was obtained using
$$\begin{gathered} (\rho - \rho _0 ) = 1.920[1 - exp( - 0.65 \times 10^{ - 3} t)] - 0.400[1 - exp ( - 0.192 \times 10^{ - 2} t)] \hfill \\ - 0.230[1 - exp ( - 0.172 \times 10^{ - 3} t)]\mu \Omega m \hfill \\ \end{gathered} $$
This analysis was also applied to earlier results on lower purity α plutonium, and to a Pu-1% Np alloy.
