Experimental evidence for temperature effect on energy loss of low-energy D+ in liquid lithium

    Corresponding author: FANG Kai-Hong,

Abstract: In order to investigate the temperature effect on the stopping power of liquid lithium material for keV D+, the excitation functions of the α-particle yields for the 6Li(d,α)4He reaction in liquid lithium (495--600 K) have been measured for the bombarding energies from 50 to 70 keV by 2.5 keV steps. The observations show that the thick-target α-yield increases statistically as lithium temperature increases. These phenomena revealed that the only possible reason is a temperature effect on the stopping power, i.e., increasing temperature resulting in a lower stopping power. As the lithium temperature increased from 495 to 600 K, the energy loss of deuterons decreased about 6.7% in the energy region of E<70 keV.
