I thik to the vast majority of nuclear physicists, fission is a process produced by the interaction of neutrons–neutral particles–and nuclei, while fusion is a process produced by the interaction of charged nuceli with each other. The names, like many names in physics and elsewhere, have historical origns, but do not show thier actual meaning on the surface. The techncial meaning of “chaos” is another example, since motions that a physicist would term “chaotic” are not random or thermal as a non-technical meaning of chaos implies.
Since pB11 is produced buy the interactions of charged nuclei, everyone would call it fusion, even though the final nuclei are smaller than one of the initial nuclei.
