Production of a monochromatic γ-ray beam by a Li7(p, γ)Be8 reaction

A procedure is described for producing a monochromatic beam of 17.6 and 14.8 MeV -rays. Energy calibrations are reported for a single-crystal total-absorption -spectrometer and for the proton beam of an electrostatic generator during the resonant capture of protons by lithium target nuclei in a Li⁷(p, )Be⁸ reaction.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, Vol. 12, No. 5, pp. 18–21, May, 1969.The authors thank E.
