Detection of the Even Parity, J=0-3, Autoionizing 4 Dnl Rydberg States of Strontium by 2-Step Laser Optogalvanic Spectroscopy (Journal article)

Jimoyiannis, A./ Bolovinos, A./ Tsekeris, P.

We have measured the energies of a few hundreds of even parity, J = 0-3 autoionizing 4 dnl Ry states of strontium using an optogalvanic spectroscopy technique. These states are reached by a two-step pulsed dye laser excitation from the 4d 5s metastables through the 4d 5p 3P0,1,2 intermediate states. Electronic collisions populate the 4d 5s states in a d.c. glow discharge through a Sr plus He vapour in a heated quartz cell. The electronic configuration for the majority of the observed Sr states is deduced from their quantum defect values and other characteristics of the corresponding transitions.
