From theCambridge English Corpus
This means that the most general condition for linear radiative instability requires that thespontaneousemissionexceeds the absorption minus the stimulated emission.
From theCambridge English Corpus

From theCambridge English Corpus
Thespontaneousemissionand gain formula are derived and compared with the case of the auxiliary undulator discussed in the previous section.
From theCambridge English Corpus
The calculation does not includespontaneousemission, but classical electrodynamics tells us that oscillating charges will emit electromagnetic radiation at the frequency of oscillation.
From theCambridge English Corpus
Accordingly, we assumespontaneousemissioninto just one mode to be the starting condition for the time-domain model as well.
From theCambridge English Corpus

From theCambridge English Corpus
Rutkevich et al. (1996) found that thespontaneousemissionof sound waves from strong shocks in metals results in corrugation of a planar shock front.
From theCambridge English Corpus
The thin solid line, the broken line, and the thick solid line denote the transition by electron collision, thespontaneousemission, and the absorption of the photon, respectively.
From theCambridge English Corpus
