• The line shape, line width and other properties of self-absorbed line are discussed introducing several models on the spatial distributions of the emitting and absorbing atoms. The simple models in which the emitting atoms decrease linearly from the center to the outside proves to be sufficient to explain the general views on the self-absorption. The shapes of the visible triplet lines emitted Hg^<198> and Cd^<114> lamps are observed without being disturbed hyperfine structure of isotopes using a direct recording Fabry-Perot interferometer. From these observations, the effect of self-absorption of these lines is made clear and is shown to agree well with the results theoretically obtained. Moreover it is found that Hg^<198> and Cd^<114> lamps can be approximately represented the model in which the emitting atoms decrease linearly from the maximum at the center to zero at the wall. The values of absorption parameter evaluated are able to be explained consistently, taking the population and decay time of the triplet states and their quenching due to collisions with carrier gas and electrons into consideration.
