Thomson scattering was used to measure the Langmuir wave spectrum generated by stimulated Raman scattering. This experiment detected Langmuir waves with components both parallel and antiparallel to the incident laser{close_quote}s wave vector {ital k}{searrow}{sub 0}. The parallel component was attributed to stimulated Raman scattering. However, the Langmuir waves moving antiparallel to {ital k}{searrow}{sub 0}, which cannot be explained by stimulated Raman scattering, were attributed to the Langmuir decay instability. {copyright} {ital 1996 The American Physical Society.}
