Scientific paper
Polarimetric observations were conducted for a series of B/e/ stars in order to confirm the presence of the dust surrounding them which was detected by Allen and Swings (1976), using IR photometry. Negative results were obtained when correlations between the polarization values and several quantities related to the extended atmosphere of the objects were sought. A search for systematic differences between the polarizations in B/e/ and Be stars shows such differences to be independent of wavelength, yielding figures of 1.0 percent in U, 0.9 percent in B, and 1.1 percent in V.
