I know plenty of physics, but "ponderomotive potential" is not in my vocabulary. This paper says
"Consider the paraxial wave function of an electron
travelling at a relativistic velocity v along the axial z-
direction, ψ(r, t) = exp(iγm(v_z−c^2t)/ℏ)ψ_⊥(x, y, t), with m
the electron mass, γ = 1/sqrt(1 − v^2/c2) the relativistic
factor and ψ_⊥ the transverse electron wave shape. The
electron shall be illuminated by a short laser pulse of
moderate intensity, described by a vector potential A(r, t)
with a temporal profile extending over 100 optical
periods. Following [53] and neglecting the transverse
electron motion, the light-induced velocity modulation, as
well as electron-positron mixing, we can approximate
the interaction by an effective scattering phase...."
So I would need to read [53]:
