This is almost certainly detailed paper that the one pager <A New Method of Measuring Nuclear Magnetic Moment> promises at the end, they mention:
> In two letters to this journal, we reported briefly on a new precision method of measuring nuclear moment, and on some results. In this paper we shall give a more detailed account of the method, apparatus and results.
and reference <A New Method of Measuring Nuclear Magnetic Moment>.
