Abstract: | The influence of the local-field on the photoabsorption cross
section of the atomic silver is studied in detail by using the
Clausius--Mossotti (CM) model and the Onsager model separately. The
variations of the photoabsorption cross section of atomic silver
with number density and radius of the environmental interaction
cavity are studied systematically by using more general expressions
for the photoabsorption cross sections, proposed by Sun et
al recently. It has proved to be reasonable to model the optical
response properties of bulky material by coupling the property of
isolated atom with the environmental effects in the present work. |
