Average charge states of heavy atoms in dilute hydrogen
Abstract
We measured the average electronic charge <q> of heavy ions with atomic numbers Z=89 through 116 traversing dilute hydrogen gas with velocities ranging from 1 to 2.6 times the Bohr velocity. We observe a strong linear dependence of the average charge on the velocity of the ions, and only a weak dependence on their atomic number Z. A more detailed examination of the experimental results shows that the <q> values reflect the influence of the 5f electron shell on the properties of these elements.
