One should distin- guish between primary nuclei, i.e. nuclei accelerated at the source and injected in the intergalactic space, and secondary nuclei and nucleons, i.e. particles pro- duced as secondaries in the photo-disintegration chain. In particular, the flux of secondary nuclei and nucleons produced in the photo-disintegration 705 Roberto Aloisio Acta Polytechnica chain of primary A0 is obtained by the numerical computation of A0 nested integrals and this computa- tion should be repeated each time the hypothesis on sources (injection and distribution) is changed.	cache/ap-1953.pdf	txt/ap-1953.txt
