[snip] 23.8 MeV alphas could create spallation neutrons from Pd that still have the necessary 7.2 MeV minimum energy required to split C12 into 3 He4.
For that matter, such an alpha could do the job itself if close enough. BTW the spallation itself will usually consume 5-10 MeV depending on the nucleus that the neutron is removed from. For that matter, it may come from a D nucleus, requiring only 2.2 MeV to free it, which would mean that the original particle would need at least 7.2 + 2.2 ~ 9.4 MeV.
