Two-Photon Laser Spectroscopy of Autoionizing Rydberg Series of Atomic Tin
Chin. Phys. Lett. 1992, 9 (12):
Extensive new data on the even-parity autoionization Rydberg series of neutral-tin have been observed and identified by using two-photon resonant ionization laser spectroscopy and time-of-flight detection method. Observed autoionization Rydberg series are 5pnp(3/2,1/2)1,2, 5pnp(3/2,3/2)1,2,3, 5pnf3/2[5/2]2,3, 5pnp3/2[7/2]3,4, and 5pnf3/2[3/2]1,2. The second ionization limit I2 is obtained by fitting experimental data with the Rydberg formula. It is 63483.90±1.35cm-1.
