Double ionization in strong laser fields:
The classical origin of correlated electrons
Experiments on double ionization of Argon and Neon in
strong laser fields show that the electrons emerge
with momentum components parallel to the field axis
that are very similar and with perpendicular momenta
that are opposite in sign but also of similar magnitude.
A classical analysis of this process suggests that the
origin of this correlation can be found in an extension
of Wanniers 1953 analysis for double ionization to allow
for the presence of an electric field.
