Superradiant Line in the Soft-X-Ray Range
Abstract
It is shown that the 2p54d 3P1-->2p6 1S0 line of the Al3+ 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.
