Measurements of the equivalent width of the h/sub beta/ emission line and age determination of hii regions of the lmc and smc

Abstract

The equivalent width of the emission line Hβ was measured photoelectrically in 29 H II regions of the LMC and 2 of the SMC respectively. The age of these regions was obtained through a calibration of Wʜβ. A relation was found between Wʜβ and the ratio of the H II region radius to that of the embedded stellar association.
