Abstract

ABSTRACT: The new experimental results on the effective quantum numbers and term energies of the highly excited odd-parity 4s4d 3 D1, 2, 3 →4s n f 3 F2, 3, 4 Rydberg transitions of zinc have been presented. The experiment was performed using the three dye lasers simultaneously pumped by the second harmonic (532 nm) of the Q-switched Nd:YAG laser. The new observation includes the 4s n f 3 F3 (12 ≤ n ≤ 50) series excited from the 4s4d 3 D2 intermediate level. In addition, the 4s n f 3 F2 (12 ≤ n ≤ 28) and 4s n f 3 F4 (12 ≤ n ≤ 33) series are observed from the thermally populated 4s4d 3 D1, 3 fine structure components. The ionization potential of zinc has been determined from the unperturbed 4s n f 3 F3 series as 75769.31 ± 0.15 cm −1, which is in excellent agreement with the previously reported value.
