Variational calculation of positronium-helium-atom scattering length
(2001-08-01)
A basis-set calculation scheme for S-waves Ps-He elastic scattering below the lowest inelastic threshold was formulated using a variational expression for the transition matrix. The scheme was illustrated numerically by ...

Rayleigh scattering in dense fluid helium
(Oxford University Press, 2018-01)
Iglesias et al. showed that the Rayleigh scattering from helium atoms decreases by collective effects in the atmospheres of cool white dwarf stars. Their study is here extended to consider an accurate evaluation of the ...
