Query: The interaction of excited atoms and few-cycle laser pulses   This work describes the first observations of the ionisation of neon in a
metastable atomic state utilising a strong-field, few-cycle light pulse. We
compare the observations to theoretical predictions based on the
Ammosov-Delone-Krainov (ADK) theory and a solution to the time-dependent
Schrodinger equation (TDSE). The TDSE provides better agreement with the
experimental data than the ADK theory. We optically pump the target atomic
species and demonstrate that the ionisation rate depends on the spin state of
the target atoms and provide physically transparent interpretation of such a
spin dependence in the frameworks of the spin-polarised Hartree-Fock and
random-phase approximations.
