OK, so no fusion: The protons lack the energy to pass the coulomb barrier and the neutrons have a half live of just 10.2 minutes.BDanielMayfield wrote:It's interesting about the continuing fusion producing phosphorus Art. I wouldn't have thought the conditions would be extreme enough this long after the SN blast. Must read more about it...After reading the links you quoted I remain unconvinced about fusion still being able to proceed after 350 years of cooling and dispersion in Cas A. What is the P producing reaction that is allegedly still ongoing?neufer wrote:
A little fusion & a little fission is still taking place.
However, before the neutrons decay away over the first few hours they can interact with stable silicon isotopes to produce unstable silicon31 which then beta decays into stable phosphorus31. https://www.youtube.com/watch?v=pxrPaNDvaQE
