The thick-target yield of the ⁹Be(d, α ₀)⁷Li and ⁹Be(d, α ₁)⁷Li^* reactions has been first directly measured over deuteron energies from 66 to 94 keV. The obtained S(E _i) of α ₀ and α ₁ have similar trends calculated by the thin-target yield, consistent with Yan’s report within the errors. Furthermore, the parametric expression of S(E) was obtained to calculate the theoretical thick target yield, and it roughly agrees with the experimental thick target yield.

⁹ Be( d , α ₀ ) ⁷ Li 和⁹ Be( d , α ₁ ) ⁷ Li ^*反应的厚靶产率首先在 66 到 94 keV 的氘核能量范围内直接测量。得到的α ₀和α _1的S ( E _i )具有相似的趋势，由薄靶产量计算得出，与 Yan 的报告在误差范围内一致。此外，S ( E ) 用于计算理论厚靶良率，与实验厚靶良率大致相符。
