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 />

a = 0.175 mm, D,/aa = 1.00, p = 0, and D 2 = 0.<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
