Sub-Poissonian angular momentum distribution near threshold in atomic ionization by short laser pulses
We analyze the angular momentum distribution of electrons near threshold in atomic ionization by short laser pulses. The radial fanlike pattern in the two-dimensional momentum distribution observed in experiments is controlled by the dominance of a few angular momenta of the order l0. We find a semi...
