Abstract
During light minimum phase, R CrB shows a broad emission line spectrum of He I including λ 10830, λ 7065, λ 7281, λ 3889, λ 6678 and λ 3188. But λ 5876 is very weak. The observed intensity ratios of (λ 3889)/I(λ 5876) and I(λ 7065)/I(λ 5876) were greater than 1. The anomalous intensities of these lines appear to be due to optical depth efects. Peliminary analysis is presented to derive the physical conditions of the emitting gas.
