Resolution of the Ba (6pjndj)1 and (6pjndj)3 autoionizing states and their mixing with the (6pjns1/2)1 and (6pjngj)3 states
Abstract
We report the resolution of the Ba (6pjndj)J=1 and (6pjndj)J=3 autoionizing levels and their mixing with the (6pjns1/2)J=1 and (6pjngj)J=3 states by a three-step laser excitation approach. For the 6p1/2ndj levels we are unable to discern a difference between J=1 and J=3. For the 6p3/2nd levels we are able to identify the two J=3 states, but only one J=1 feature, and measure their quantum defects. Furthermore we are able to measure the mixing of the (6p3/2ndj)J=1 states with the (6p3/2ns1/2)J=1 states and determine that the analogous mixing of the (6p3/2ndj)J=3 states with the (6p3/2ngj)J=3 states is not observable, nor is any mixing of the 6p1/2ndj states with either 6p1/2ns1/2 or 6p1/2ngj states.
