Observation of an electric quadrupole transition in a negative ion: Experiment and Theory
C. W. Walter, S. E. Spielman, R. Ponce +4
The first direct experimental observation of an electric quadrupole (2) transition between bound states of an atomic negative ion has been made. The transition was obse…

Predicting quasibound states of negative ions
M. S. Safronova, C. Cheung, M. G. Kozlov +3
We demonstrated the accurate prediction of a quasibound spectrum of a negative ion using a novel high-precision theoretical approach. We used La as a test case due to a recent…

Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
