Title: Decay of H atoms excited in small electric fields

Journal Article · · Phys. Rev. A; (United States)

The branching ratios for radiative decay of H atoms excited in small electric fields (0--5 Vcm) have been calculated for the nl states up to n = 6. A simple computational procedure was employed, allowing only for Stark-effect mixing of levels with the same values of the quantum numbers (n,j,m/sub j/). The results are compared with more detailed calculations available for 3l-state decay made using the density-matrix formalism, and new calculations of this type reported here for 4l-state decay. In conjunction with theory, this allowed the domain of validity of the simple computational procedure to be established as a function of n. The results show that the branching ratios depend quite strongly on electric-field magnitude, pointing to the need to exercise caution in measurements of H emissions, and in application of the available data to other problems.
