Abstract

It is shown that the

2 p^{5} 4 d {}^{3}P_{1} \to 2 p^{6} {}^{1}S_{0}

line of the

{Al}^{3 +}

ion at a wavelength of 117.41 Å is superradiant in a dense laser-produced plasma. The measured gain in a two-plasma experiment is 17%. The gain coefficient is of the order of 10

{cm}^{- 1}

with a lower limit of 2.5

{cm}^{- 1}

and an upper limit of 22

{cm}^{- 1}
