报道了能量接近340 MeV/核子的高能重离子的能量分辨率，并使用填充有90%Ar/10%CH4气体混合物的气体电离室测量。我们观察到，能量分辨率是成正比的入射离子的原子序数的倒数和气体厚度的平方根的倒数。这些结果与Bethe-Bloch带电粒子能量损失公式和Bohr重离子能量离散公式一致。此外，还讨论了探测器中产生的高能δ射线对能量沉积的影响。
The energy resolution is reported for high-energy heavy ions with energies of nearly 340 MeV/nucleon and was measured using a gas ionization chamber filled with a 90%Ar/10%CH4 gas mixture. We observed that the energy resolution is proportional to the inverse of the atomic number of incident ions and to the inverse-square-root of the gas thickness. These results are consistent with the Bethe–Bloch formula for the energy loss of charged particles and the Bohr expression for heavy ion energy straggling. In addition, the influence of high-energy δ-rays generated in the detector on the energy deposition is discussed.
