Plot of $[\overline i\left(k \right)]$ , the average of $[i\left({\bf{k}} \right)]$ of equation (1)

on the sphere of $[\left| {\bf{k}} \right| = k]$ (black line), and $[{\sigma _c}]$ of equation (13)

(blue line) for lysozyme (a) and the HslUV complex (b). The intensities assumed are I_i = 5 ×10²¹ and 5 ×10²⁰ photons pulse^-1 mm^-2, respectively.
