Description
This paper describes first the application of neutron depth profiling (NDP) for measuring the distribution of 6Li in LiAlO2 ceramics. Using a surface barrier detector for detecting 3H produced in 6Li(n, α)3H, 6Li was profiled to a depth of 14 μm in the ceramics. Secondly, a new methodology is presented for NDP with enhanced capabilities based on measuring the energy of recoiling nuclei from (n, p) and (n, α) reactions by time-of-flight mass spectrometry. The scope of recoil nucleus time-of-flight mass spectrometry (RN-TOF-MS) includes profiling of 10B, 14N, 17O, 33S, 35Cl, 40K. Probe depths may be of a few tens nanometers. RN-TOF-MS complements and refines NDP based on charged particle (p or α) spectrometry. (author) 7 refs.; 6 figs.; 1 tab
