Description

The reaction rate and subsequent cross section enhancement to the ${}^7\mathrm{Li}{(}^1\mathrm{H},\alpha )\alpha$ reaction was measured in samples of lithium tungstate (${\mathrm{Li}}_2{\mathrm{WO}}_4$), lithium manganate (${\mathrm{LiMn}}_2{\mathrm{O}}_4$), lithium titanate spinel (${\mathrm{Li}}_4{\mathrm{Ti}}_5{\mathrm{O}}_{12}$), and lithium iron phosphate (${\mathrm{LiFePO}}_4$) at lab frame beam energies of 100 keV, 200 keV, 500 keV, and 1 MeV using the Tandetron system at Western University.
Analysis is ongoing but calculations suggest a strong enhancement as high as a factor of ~4 for the manganate, titanate, and iron phosphate at 100 keV, with the enhancement decreasing to within theoretical values as incident energy increased to 1 MeV.
The lithium tungstate values on the other hand remained closer to theoretical (bare values taken from ENDFVIII) across the energy range tested, a result that aligns well with values reported in literature.
