我们在这里报告的半经验和理论预测之间的比较，在微分和总截面的质子诱导电离的孤立腺嘌呤分子。而第一个是由现有的分析模型，第二个是基于两个量子力学模型最近开发的第一玻恩和连续扭曲波近似，分别。此外，还报道了大量的实验数据以供比较。在这里调查的所有运动学条件下，我们已经观察到一个非常好的理论和实验之间的协议，而强烈的差异，特别是当双微分截面分析的半经验模型。
We here report a comparison between semi-empirical and theoretical predictions in terms of differential and total cross sections for proton-induced ionization of isolated adenine molecules. Whereas the first ones are provided by existing analytical models, the second ones are based on two quantum-mechanical models recently developed within the 1st Born and the continuum distorted wave approximation, respectively. Besides, a large set of experimental data is also reported for comparisons. In all kinematical conditions here investigated, we have observed a very good agreement between theory and experiment whereas strong discrepancies were reported with the semi-empirical models in particular when doubly-differential cross sections are analysed.
