摘要: The number of neutrons evaporated by nuclei excited $\mathrm{Li}(p,\ensuremath{\gamma})$ photons is calculated along the compound nucleus formalism. It found, for light nuclei, to be very small and exhibit an odd-even alternation. From experimental cross sections photoneutron production at 17 Mev, section photocapture deduced, found proportional $Z$ within 25 percent. Material presented application formalism in particular a formula density levels.
