WebIf P i and P f are non-negligible when n i and n f are nonzero, and E d depends strongly on n f, then interactions with the material electrons must be considered.We will later show that this makes σ in eqn (3) larger than σ 0 in eqn (2) for all beam energies, most prominently when ε b < ε c.. The remainder of this section focuses on the derivations of P i, P f, and E d. WebWhy does boron have 3 valence electrons?
