Fig. 6. M<strong>in</strong>ima <strong>of</strong> the <strong>in</strong>tensity pr<strong>of</strong>iles for different positions <strong>of</strong><br />
the absorb<strong>in</strong>g wire. The experimental po<strong>in</strong>ts <strong>of</strong> Table 1 are plotted.<br />
The solid curve is obta<strong>in</strong>ed from Eq. (25) with L = 10.0 mm,<br />

aExperimental displacements <strong>of</strong> an absorb<strong>in</strong>g rod parallel to the slab are<br />
compared with those obta<strong>in</strong>ed from the correspond<strong>in</strong>g fits. The distance<br />
between the rod and the boundary (x position) is 4.30 ± 0.02 mm, and the<br />
thickness <strong>of</strong> the cell is 10.0 mm. The scatter<strong>in</strong>g contribution is neglected<br />
(p = 0), and the diffusion constant <strong>in</strong>side the rod is small (D 2
