Abstract

The light attenuation technique has been modified to expand the range of its applicability up to AL values of 460. This has been accomplished through the use of a laser as the source of monochromatic collimated light, and a very sensitive low-bias picoammeter.

The data obtained using the photographic technique were found to agree reasonably well with those from light attenuation.

Abstract

On a modifié la technique d'atténuation de la lumière pour étendre son applicabilité jusqu'aux valeurs de 460 pour AL. Cela a été accompli en employant un laser, comme source de lumière monochromatique collimatée. ainsi qu'un picoampèremètre très sensible et à faible polarisation.

On a constaté que les résultats obtenus en employant la technique photographique concordaient raisonnablement bien avec ceux fournis par la méthode d'atténuation de la lumière.
