Upper Limit on the Magnetic Dipole Contribution to the 5p-8p Transition in Rb by Use of Ultracold Atom Spectroscopy

R. Pires, M. Ascoli, E. E. Eyler +2

We report on hyperfine-resolved spectroscopic measurements of the electric-dipole forbidden 5$p_{3/2}\to 8p_{1/2}$ transition in a sample of ultracold ${}^{87}$Rb atoms. The hyperfi…
