Photoionization of the francium 7P 3/2 state
We have measured the non-resonant photoionization cross section of the 7P 3/2 state of francium for 442 nm light to be 20.8 ± 7.1 Mb. Atoms were irradiated in a magneto-optical trap, and we deduce the photoionization rate from the change in trap lifetime. The result is consistent with a simple extra...

Summary: | We have measured the non-resonant photoionization cross section of the 7P
3/2
state of francium for 442 nm light to be 20.8 ± 7.1 Mb. Atoms were irradiated in a magneto-optical trap, and we deduce the photoionization rate from the change in trap lifetime. The result is consistent with a simple extrapolation of known cross sections for other alkali atoms. |
