Photodisintegration ofLi6

Abstract

The photodisintegration of ${\mathrm{Li}}^{6}$ by bremsstrahlung radiation of 17.3-Mev peak energy was investigated by use of coincidence techniques to detect neutron-proton coincidences and by measurement of the photo-proton energy spectra. The ${\mathrm{Li}}^{6}(\ensuremath{\gamma}, n){\mathrm{Li}}^{5}$ reaction is found to be responsible for 0.58\ifmmode\pm\else\textpm\fi{}0.13 of the photoneutron yield measured by Romanowski while the ${\mathrm{Li}}^{6}(\ensuremath{\gamma}, p){\mathrm{He}}^{5}$ reaction contributes 0.31\ifmmode\pm\else\textpm\fi{}0.04 of the yield. No angularly correlated neutron-proton coincidences were detected which would support a deuteron-alpha-particle model for the ${\mathrm{Li}}^{6}(\ensuremath{\gamma}, np){\mathrm{He}}^{4}$ reaction; however, the possible existence of this reaction is not eliminated.
