7{ital S}{sub {bold 1/2}}{r_arrow}9{ital S}{sub {bold 1/2}} two-photon spectroscopy of trapped francium
- Department of Physics, State University of New York, Stony Brook, New York 11794-3800 (United States)
We report on the spectroscopic measurement of the {sup 210}Fr 9{ital S}{sub 1/2} energy obtained by two-photon excitation of atoms confined and cooled in a magneto-optic trap. The resonant intermediate level 7{ital P}{sub 3/2} is the upper state of the trapping transition. We have measured the energy difference between the 9{ital S}{sub 1/2} state and the 7{ital S}{sub 1/2} ground state to be 25671.021{plus_minus}0.006 cm{sup {minus}1}. {copyright} {ital 1996 Optical Society of America.}
