摘要：
Concentrations of deuterium (D) and lithium (Li) in titanium (Ti) were measured with nuclear reaction analysis (NRA) method. With Delta E&E-counter-telescope, proton peaks by the D(d,p)T and Li-6(d,p)Li-7 reactions were well resolved from continuous spectrum of alpha-particles by the Li-7(d,alpha + n)alpha reaction. The yields of these protons were obtained and densities of deuterium and lithium isotopes on the Ti surfaces were obtained. Isotopic ratio of lithium was determined by comparing the yield of Li-6(p,3He)alpha, Li-6(p,alpha) He-3 and Li-7(p,alpha)alpha reactions with proton beam bombardment. Deviation among the experimental values was about 9%. (C) 2000 Elsevier Science B.V. All rights reserved.
