• We conducted precise measurements of electrical mobilities of negatively charged metal nanoparticles in Ar gas using a differential mobility analyzer. The measured inverse mobilities were larger than those calculated from the hard-sphere collision model. We propose a formula describing the relationship between the electrical mobilities and the diameters of particles measured using transmission electron microscopy, which corrects the deviation from the hard-sphere collision model.
