H, He-like recombination spectra II: -changing collisions for He Rydberg states
F. Guzmán, N. R. Badnell, R. J. R. Williams +3
Cosmological models can be constrained by determining primordial abundances. Accurate predictions of the He I spectrum are needed to determine the primordial helium abundance to a…

The late time structure of high density contrast, single mode Richtmyer-Meshkov flow
R. J. R. Williams
We study the late time flow structure of Richtmyer-Meshkov instability. Recent numerical work has suggested a self-similar collapse of the development of this instability at late t…
