Abstract

We have measured the lifetimes of (

1 s 2 p

)

{}^{3}P_{0, 2}

in heliumlike fluorine in a search for the nuclear-spin-induced quenching of the

{}^{3}P_{0}

state. Both fine-structure decays (

2 {}^{3}S_{1} - 2 {}^{3}P_{0, 2}

) were observed following foil excitation of a 15-MeV F beam. Within experimental error (±10%) the two states have the same lifetime (10 nsec) in agreement with theoretical

2 p - 2 s

E 1

decay rates.
