FLsin(θ)=Fa
The attractive force between the electrons is the Lorentz's force. Fa is the force in the plane of the orbit that keeps the orbital radius constant due to the attraction of the neighboring orbit.
tan(θ)=Δr2ae
FL=neq24εo(2ae)2cos2(θ)=neq24εo(2ae)24a2e(2ae)2+(Δr)2=neq24εo1(2ae)2+(Δr)2
Therefore,
Fa=neq24εo(2ae)2(2ae)2(2ae)2+(Δr)2(Δr)√(2ae)2+(Δr)2
Fa=neq24εo(Δr){(2ae)2+(Δr)2}3/2
Δr=r−re
Fa=neq24εor−re{(2ae)2+(r−re)2}3/2
A brand new attractive force! And we have,
mec2re=Ac2+Gmamer2e+neq24εor−re{(2ae)2+(r−re)2}3/2−Zq24εo(re−rp)2−TnTe4πτor2e
a new expression for the forces in action on an orbiting electron. Under normal circumstances,
r=re and Fa=0
But this force will definitely play a part in ionization.
2ae is twice the radius of an electron, and ne the number of electrons in orbit minus one. We are assuming that the orbiting electrons are stacked closest possible in parallel orbits.
