A Radiative Cycle with Stimulated Emission from Atoms (Ions) in an astrophysical Plasma

S. Johansson, V. S. Letokhov

We propose that a radiative cycle operates in atoms (ions) located in a rarefied gas in the vicinity of a hot star. Besides spontaneous transitions the cycle includes a stimulated…
