摘要：

We report results on the pulsed field ionization threshold photoelectron spectroscopy of the A 2SIGMA+ state of N2O+, using coherent extreme ultraviolet for single Photon ionization. For variable delays up to 1 mus between excitation and ionization no significant change in the threshold signal was observed, in spite of the 250 ns radiative lifetime of the excited ion core. The rotational profiles of the (000) and (100) bands were simulated by the standard model for rotational linestrengths in photoionization, and these results reveal information on the dynamics of the Rydberg states involved in pulsed field ionization.
