论文摘要
我们研究了对生物学兴趣分子的多材离子的电离横截面的缩放规则。横截面是使用[Mendez等人中提出的方法获得的。 J. Phys B（2020）]，它考虑了与分子化学计量模型结合的原子靶标的扭曲的波浪计算。我们检查了用+1到+8的核电荷兰离子对五个核苷酸酶，细胞儿童，鸟嘌呤，胸腺嘧啶，尿嘧啶，四氢呋喃，嘧啶和水的影响。我们研究了电离横截面的缩放规则，其离子电荷和每个分子的活性电子数量。结合了这两个特征，我们为任何离子和分子靶标的缩放定律，在中间至高能量范围内有效，即0.2-5 MeV/amu，以实现氧气影响。因此，这里分析的40个离子分子系统可以合并为单个频段。我们通过多个碰撞系统确认我们独立缩放法的一般性。
We investigate scaling rules for the ionization cross sections of multicharged ions on molecules of biological interest. The cross sections are obtained using a methodology presented in [Mendez et al. J. Phys B (2020)], which considers distorted-wave calculations for atomic targets combined with a molecular stoichiometric model. We examine ions with nuclear charges Z from +1 to +8 impacting on five nucleobases -adenine, cytosine, guanine, thymine, uracil-, tetrahydrofuran, pyrimidine, and water. We investigate scaling rules of the ionization cross section with the ion charge and the number of active electrons per molecule. Combining these two features, we define a scaling law for any ion and molecular target, which is valid in the intermediate to high energy range, i.e., 0.2-5 MeV/amu for oxygen impact. Thus, the forty ion-molecule systems analyzed here can be merged into a single band. We confirm the generality of our independent scaling law with several collisional systems.
