【 摘 要 】

We present a new method for measuring electron impact ionization cross section of molecules through Coulomb crystallization of the product ions in a linear Paul trap.. The idea of electron impact ionization cross sections measurements is described, and the technique is analyzed in terms of its efficiency and some specific apparatus effect.
