In this project in the Physical Chemistry Program, Viehland will develop a theory of the way ion velocities are distributed when trace amounts of ions move through dilute gases under the influence of electric fields. Computer programs have been developed that will allow both the ion velocity distribution and the gaseous ion transport coefficients to be calculated from knowledge of the ion-neutral interaction potentials. Comparison of the calculated quantities with experimental results gives insight into the accuracy with which the distribution function can be measured and also into the accuracy of present microscopic knowledge about the forces between individual ions and atoms.

在物理化学计划的这个项目中，Viehland将开发一种当微量离子在电场的影响下通过稀气体时离子速度分布的理论。计算机程序已经开发，这将允许离子速度分布和气态离子输运系数计算从离子中性相互作用势的知识。计算的数量与实验结果的比较，使洞察的准确性，可以测量的分布函数，也到目前的微观知识的准确性，个别离子和原子之间的力量。
