Certain quartet levels in alkali-like systems retain metastability against autoionization while acquiring large radiative yields. This quasi-metastability occurs through selective coupling to non-autoionizing doublet levels by the spin-orbit interaction. An example of such a level is the 5p/sup 5/5d6s /sup 4/P/sub 5/2/ level of neutral Cs, which has a calculated branching ratio for radiation at 1091 A of 43%. Experimentally, we find that this line has an emission intensity equal to 1/6 of that of the strongest ion line of Cs/sup +/, and is a promising candidate for an extreme ultraviolet laser.
