EXPERIMENT AND THEORY FOR THE REACTION LI-7(GAMMA,T)HE-4 FOR E-GAMMA LESS-THAN 50 MEV

Differential and total cross sections for the Li7(γ,t)He4 reaction were measured. Both real and virtual photons were used in the experiment and gave self-consistent results. The data show a broad resonance indicating the presence of positive parity states near 8 MeV excitation in Li7. A calculation using an α-H3 cluster model of Li7 was also performed. Poor agreement is found between the calculation and experimental results.
