Abstract

The ⁷Li (p,p'γ)⁷Li reaction cross section and photon yield from a thick lithium target at proton energies from 0.7 to 1.85 MeV have been measured with a HPGe gamma-ray spectrometer. The spectrometer is calibrated on total and relative sensitivity by reference radionuclide sources of photon radiation. The measurement results are compared with those presented in the EXFOR nuclear reaction database and with other data published in open sources. The reliability of the results of previous studies is analyzed.
