We investigate a possibility of using γ-ray-generating nuclear reactions for absolute measurements of bulk ion temperature in D-^3He fusion plasma. Radiative capture processes between fuel ions and specific γ-ray modes of nuclear reactions induced by a small admixture of ^6Li are examined for such an application. It is shown that ion temperature can be determined by comparative measurements of the respective γ-ray yields. An essential point of the method proposed is that any fluctuations of plasma parameters during the measurements do not affect accuracy of temperature probe. Nuclear reactions ^3He(^3He,γ)^6Be and ^6Li(^3He,γp)^8Be are suggested for diagnostics for the first time. Necessary data on reaction cross sections and Maxwellian rate parameters are calculated.
