The flight trajectories of three group of electrons with initial KE of 5 eV, 60 eV, and 95 eV, respectively. The two electrons of each group are emitted from two radial positions. The two initial positions e1 and e2 are shown in the left enlarged view. In the right enlarged view, P is the intersection spot of the electrons with 95 eV, Q is the intersection spot of electrons with 60 eV, and S is the intersection spot of electrons with 5 eV. In addition, the equipotential lines are shown.
