摘要：

The 2-photon resonant, 3-photon ionization spectrum of gaseous atomic copper is presented. The (2)D(5/2)3d(10)nd <-- (2)S(1/2)3d(10)4s (n = 9-21) Rydberg series is observed in 2-photon excitation. The term energies of this series converge to the lowest ionization threshold with an apparent quantum defect of 0.92. The state which couples the ground (2)S(1/2)3d(10)4s state of copper to the (2)D(5/2)3d(10)nd Rydberg series is a non-stationary state composed primarily of the spin-orbit components of the lowest P-2(0) atomic states.
