使用硅探测器的α光谱测量是测定α发射锕系元素的标准方法。该方法需要制备用于分析的源，其不会通过样品自吸收使发射的α粒子的能谱降级。文献中报道了多种用于电沉积锕系元素的方法，其中许多方法需要长的沉积时间并且缺乏重现性。一个硫酸盐为基础的方法进行了评估，这些源的制备使用化学计量学分析，以优化方法，并评估几个变量和它们的相互作用的目标，以实现高产率源制备在1小时或更少。
Alpha-spectrometric measurements using Si detectors is the standard method for the determination of alpha emitting actinide elements. This method requires the preparation of sources for analysis which do not degrade the energy spectrum of the emitted alpha particles via sample self-absorption. A variety of methods for the electrodeposition of actinides have been reported in the literature, many of which require long deposition times and lack reproducibility. A sulfate based method has been evaluated for the preparation of these sources using chemometric analysis to optimize the method and evaluate several variables and their interactions with the goal to achieve high yield source preparation in 1 hour or less. Typical resolution for this method is 30 keV or less with recoveries approaching unity.
