Four B stars, ..cap alpha.. Vir, ..beta.. Cen, ..cap alpha.. Gru, and ..beta.. Lib, were observed with the Copernicus Princeton Telescope Spectrometer at a resolution of 0.1 A in order to investigate the presence of chromospheric emission. Emission was observed in ..beta.. Cen and ..cap alpha.. Gru, while the results for ..cap alpha.. Vir and ..beta.. Lib were inconclusive. (AIP)
