摘要：

The medium resolution (R=1000) near infrared spectra of 30 early type Be stars obtained during the period October 1998-April 1999 are presented. The Paschen beta and Brackett gamma lines are seen in emission in majority of these stars. The higher order Brackett series lines from m=10 to 19 are detected in emission with significant strength compared to the Brackett gamma emission line flux indicating the effect of optical depth. The Fe II line at 1.6873 mum is detected in a small number of stars indicating existence of higher density and lower temperature emission zone.
