In order to investigate the interaction of d-Li, the excitation functions of α-particle yields for the 6Li(d, α)4He reaction in liquid Li (495–600 K) have been measured for the bombarding energies from 30 to 70 keV by 2.5 keV steps. It turns out that the excitation function is significantly affected by the environmental temperature, and this results in a negative T-dependence for both screening potential and energy loss. The T-dependence of the screening energy can be simply explained by the reduced Debye-Hueckel model due to the ionic screening, while the experimental evidence of the T-dependence energy loss is presented only for calling a more reasonable explanation.
