I want to know the answer to the following question:
What is mixed with tritium and experiences nuclear fusion in a fission/fusion bomb?
All the background I'm provided with is that "Such bombs are jacketed in a non-fissile (unenriched) uranium case, and they derive more than half their power from the fission of this material by fast neutrons from the nuclear fusion process.". Is that enough to answer the question?
Answer: no
