Plasma-Material Interaction Data Set 57

Recombination of D in Cu

$$ K_\mathrm{r} = K_\mathrm{r0} \exp\left(-\frac{E_\mathrm{r}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]

Comment

Quoted in Dolan and Anderl based on an Arrhenius fit to the work of Nagasaki (two papers, 1992).
