The authors use a result of \textit{I. M. Gel'fand} [Dokl. Akad. Nauk SSSR, n. Ser. 73, 1117-1120 (1950; Zbl 0037.34505)] to give an alternative proof of an expansion formula from \textit{E. C. Titchmarsh}'s monograph [Eigenfunction expansions associated with second-order differential equations. Vol. II (Clarendon Press, Oxford) (1958; Zbl 0097.27601)].
