Figure 2.

Absorption coefficient (colored lines) as a function of photon energy. Solid lines are for α1(ω). Dashed lines are for <a onClick="popup('','MathML',630,470);return false;" target="_blank" href="">View MathML</a>, and dotted lines are for α(ω,I) = α1(ω) + α3(ω,I). The results are for R1 = 10 nm, L = 20 nm, P = 0, F = 0, and I = 2×104W/cm2. Several values of the outer radius have been considered.
