In this paper we present the results of an investigation of the 1s-2p_{+} intra-shallow-donor transition by means of an extremely difficult magnetotransmission experiment performed on semi-insulating GaAs. We report the temperature dependence of the transition intensity. We noticed the absence in the absorbance spectra of a well-pronounced structure which is observed at low magnetic fields in photoconductivity measurements. The results are discussed in terms of a fluctuating potential from ionized centres in semi-insulating GaAs.
