摘要：
This paper describes part of a project whose overall aim was the fabrication of a set of B-10 and (LiF)-Li-6 deposits of known area density for use in a measurement of the free neutron lifetime. (n, alpha) rates were measured in a neutron beam in a reproducible geometry and were related to the masses of several of the deposits (determined by isotope dilution mass spectrometry) so that the masses of the remaining deposits, and hence their area densities, could be established. Details are given here of the detection arrangement and of the corrections which have to be made to the charged particle counting rates in order that the masses and counting rates be properly correlated.
