Possibility of32Si production as a by-product of32P radioisotope production process

On the Production of No-Carrier-Added 32Si, a Potential Research Tool

“…A variety of different nuclear reactions have been used or considered by others as pathways to '^Si: 1) "C1 (p, a2p)"Si using 340 MeV [1], 420 MeV [6] and 52 MeV [8] protons 2) ''P (n, (n, p)'^Si, a sequential route considered by FORBERG [9] as the most promising method for production in a nuclear reactor 3) '^S (n, (n, p)"Si yielding '^Si as a by-product in the large-scale manufacturing of '^P in nuclear reactors [10] 4) Si (t, p)'^ Si either with tritons accelerated in a VAN DE GRAAFF machine, with enriched as the target [3], or indirectly in a nuclear reactor with Li-Si alloy as target material, the tritons being produced by the slow neutron reaction ®Li(n, a)T [11,12], The above processes with the exception of the fourth -the (t, p) reaction -give rise to a carrier-free product, at least in principle.…”
