Status of (n, charged particle) measurements at LLL. [14 MeV]

Abstract

A charged-particle magnetic-quadrupole spectrometer was used to study (n, charged particle) reactions on materials bombarded with 14- to 15-MeV neutrons. Charged-particle production cross sections, angular distributions, and spectra were measured. The materials investigated to date include most of those proposed for fusion reactor structures, Al, Ti, Cr, V, Fe, Ni, Cu, Nb, and stainless steels 304 and 316. Isotopic data on /sup 46/ /sup 48/Ti, /sup 50/ /sup 52/Cr, /sup 54/ /sup 56/Fe, /sup 58/ /sup 60/Ni, and /sup 63/ /sup 65/Cu and on the monoisotopic elements /sup 27/Al, /sup 51/V, and /sup 93/Nb provided stringent tests of reaction model calculations. Equilibrium and pre-equilibrium reaction mechanisms were identified and quantified. Preliminary data on /sup 92/ /sup 94/ /sup 95/ /sup 96/Mo and on light nuclides including /sup 12/C and /sup 7/Li were obtained recently. 8 figures, 1 table
