Sj. Rose, THE EFFECT OF ORBITAL RELAXATION IN MEDIUM AND HIGH-Z AVERAGE-ATOM CALCULATIONS, Journal of quantitative spectroscopy & radiative transfer, 53(1), 1995, pp. 39-44
The effect of orbital relaxation in average-atom calculations of the a
tomic physics of plasmas is investigated using self-consistent-held mo
dels for several elements. It is shown that for medium and high-Z mate
rials the effect of orbital relaxation, whilst being very significant
for low states of ionization, is less significant for higher states an
d that the effect of orbital relaxation varies substantially along an
isoelectronic sequence.
