The production of Gd-148 had challenges for available methods in the literature, such as its high cost and low production amount. Therefore, we recommend a new production route of Gd-148 on natural Sm and Eu targets via particle accelerators. For this aim, we calculated and simulated cross-section, activity, the yield of product, and integral yield curves for 21 different nuclear reaction processes under certain conditions. Based on the obtained results, we proposed the radioisotope Gd-148 to use Radioisotope Thermoelectric Generators for deep space and planetary explorations in spacecraft and space-probes as a suitable energy source, instead of Pu-238.
钆-148的生产对于文献中现有的方法存在挑战，例如成本高和产量低。因此，我们推荐一种通过粒子加速器在天然钐和铕靶材上生产钆-148的新途径。为此，我们计算并模拟了在特定条件下21种不同核反应过程的截面、活度、产物产率和积分产率曲线。基于所得结果，我们提议将放射性同位素钆-148用作放射性同位素热电发生器的能源，以替代钚-238，用于航天器和太空探测器的深空和行星探索。
