Scientific paper

Slit spectra at 60 A/mm covering H alpha have revealed Be stars in NGC 3766 and IC 2581. NGC 3766 is found to contain the largest number of Be stars of any single cluster studied in the Galaxy, and the high proportion of Be stars in NGC 3766 around V equal to 9 supports the finding of Schild and Romanishin (1976) that Be stars are most likely to appear in the core contraction stage of evolution. Also discussed are three giant or supergiant stars, HD 90706, HD 90707 and HD 100943, with at least incipient emission.
