Abstract

This paper describes first the application of neutron depth profiling (NDP) for measuring the distribution of⁶Li in LiAlO₂ ceramics. Using a surface barrier detector for detecting³H produced in⁶Li(n, )³H,⁶Li was profiled to a depth of 14 m 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, ) reactions by time-of-flight mass spectrometry. The scope of recoil nucleus time-of-flight mass spectrometry (RN-TOF-MS) includes profiling of¹⁰B,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 ) spectrometry.
