Abstract: | The evolution of the photoabsorption cross sections of atomic xenon
with number densities varying from ideal gas to condensed matter
has been studied by an alternative view in the present work. The
alternative expressions of the photoabsorption cross sections
presented by Sun et al recently were used with the local field
models that has proven to be generalized easily to multiatomic
systems including molecules and condensed phase systems. The present
results show that the variation of the photoabsorption cross
sections of atomic xenon in the giant resonance region from the
isolated to the condensed conditions is very small, which agrees
well with the variation law of the solid and gas experiments. |
