Many industrial problems require the nondestructive determination of the percentages of chemical elements in samples whose components have very similar physical properties.The present work is an extension of that reported in [1, 2] and tests the possibility of using a stable method of quantitative analysis of multicomponent mixtures based on experimentally determined photoneutron yields.We use the scheme of measuring photoneutron yields on a betatron proposed by O. V. Bogdankevich [3], and the mathematical apparatus for solving certain incorrectly formulated problems first proposed by A. N. Tikhonov [4] and subsequently successfully developed in papers by V. G. Shevchenko et al. for determining photonuclear cross sections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
