利用高强度短脉冲激光产生的离子碳束，我们测量了冷或等温加热的固体密度铝物质中的单发平均电荷平衡。我们证明了加热到1 eV的这类物质中的等离子体效应对能量为0.045-0.5 MeV/核子的碳离子的平衡没有显著影响。此外，这些测量还允许对半经验公式或从头计算模型进行第一次评估，这些公式或从头计算模型被用来预测轻离子通过热致密物质的平衡电荷态分布的平均值。
Using ion carbon beams generated by high intensity short pulse lasers we perform measurements of single shot mean charge equilibration in cold or isochorically heated solid density aluminum matter. We demonstrate that plasma effects in such matter heated up to 1 eV do not significantly impact the equilibration of carbon ions with energies 0.045-0.5 MeV/nucleon. Furthermore, these measurements allow for a first evaluation of semiempirical formulas or ab initio models that are being used to predict the mean of the equilibrium charge state distribution for light ions passing through warm dense matter.
