Energies and lifetimes of the 9p and 10p excited states in atomic francium

P. Lassègues, A. Ajayakumar, M. Athanasakis-Kaklamanakis +29

We present the first measurement of 9p 2P1/2,3/2 and 10p 2P1/2,3/2 excited levels absolute wavenumbers and radiative lifetime in francium. We used the Collinear Resonance Ionizatio…
