Résumé
Nous avons irradié à 21 K aux neutrons rapides, 4 échantillons de SmS dopés en phosphore (1 %). Nous avons observé un accroissement important de leur conductivité électrique, qui semble indiquer l'apparition d'ions Sm³⁺ pendant l'irradiation.

Abstract
Four SmS samples, doped with phosphorus (1 %), have been irradiated with fast neutrons at 21 K. A high increase of their electrical conductivity has been observed which seems to be due to an appearance of Sm³⁺ ions during irradiation.
