We have studied ionization and excitation of Rydberg atoms by intense sub-picosecond electromagnetic field pulses of less than one cycle duration. The ionization threshold electric field scales as the binding energy (i.e. n .-2), rather than the n ,--4 threshold scaling characteristic of static field ionization and high order multiphoton ionization. This altered behavior is due to the short duration and the subcycle nature of the field. We also find a wide distribution of final states produced
