The general profiles entering the polarised radiation transfer matrix for the hydrogen Lyα line in dense magnetised plasmas are studied. The Stark effect due to plasma electrons is treated by the Unified Theory. The contribution of fine structure is discussed. Ion dynamics effects are studied, by application of the Model Microfield Method (MMM). The validity of a simpler approach, based on the Simplified Unified Theory (SUT) is assessed, by comparison with the MMM.
