Electric field ionization of high Rydberg states of Ar with sequences of identical pulses
Novel field-ionization behavior of very high Rydberg states of Ar (n=50-250) is observed using sequential pulsed electric fields. Fast autoionization acts as a filter against adiabatic field ionization near the ^(2)P_1/2 threshold, whereas both diabatic and adiabatic field ionization occur near the...

| Summary: | Novel field-ionization behavior of very high Rydberg states of Ar (n=50-250) is observed using sequential pulsed electric fields. Fast autoionization acts as a filter against adiabatic field ionization near the ^(2)P_1/2 threshold, whereas both diabatic and adiabatic field ionization occur near the ^(2)P_3/2 threshold. Sequences of up to 9 equivalent pulses yield recurrent field ionization signals near the ^(2)P_3/2 threshold, provided that the field returns close to zero between pulses, demonstrating a statistical redistribution of the Rydberg population amongst all states of a given Stark manifold near zero field. |
