Charge Sign Effect on the Coulomb Logarithm for a Two-Component (e.g., Antihydrogen) Plasma in a Penning Trap
Abstract
The magnitude of the center-of-mass scattering angle for a collision between two charges of the same sign is the same as the magnitude of the center-of-mass scattering angle for a collision between opposite single charges. everything else being equal. However, this equivalence only applies for a Coulomb interaction of infinite range. If the range of interaction between two charged particles is limited, as in a plasma, the center-of-mass scattering angle acquires a dependence on whether the two particles have the same or opposite charge signs. In the work presented, the effect that the two different charge sign combinations can have on the Coulomb logarithm is assessed by considering a cutoff Coulomb interaction potential. A substantial effect is predicted for neutral or partially neutralized plasmas in Penning traps.
