High resolution imaging of 2D distribution of lithium in thin samples measured with multipixel detectors in sandwich...

A method that enables visualization of lateral distribution of Li in thin films is described. The method is based on the simultaneous detection of the reaction products of the ⁶Li(n,α)t nuclear reaction with thermal neutrons measured with two multipixel detectors in a sandwich geometry with a sample. Here, the principle and basic methodological parameters of the method, including tests with thin polymers with known Li microstructure, are discussed.
