A small thin NaI(Tl) scintillator has been used as both source and detector of photoprotons produced in sodium by Li/sup 7/(p, gamma ) radiation. This technique provides photoproton energy spectra of good resolution and high statistical precision. Spectra were obtained with both resonance and nonresonance radiation from the Li/sup 7/(p, gamma ) reaction which permit identification of protons produced by the 17.6 Mev component of the incident radiation. These protons correspond to transitions to states in Ne/sup 22/ at energies of 0 (0.31 mb), 1.3 (2.5 mb), 3.3 (0.6 mb), 4.4 (0.9 mb), 5.4 and 5.7 Mev (approximately 2 mb for both). This experiment establishes the existence of Ne/sup 22/ levels at the three highest energies. Previous evidence for a level between 4 and 5 Mev is discussed and is found to be compatible with the present results. (auth)
