ResumoThe g-factor of the 480 ns, 9− isomer at 2.237 MeV in 200Pb was measured by the time-differential perturbed angular distribution method. The result, g = −0.0285±0.0011 confirms the rather pure (f52−1i132−1) quasiparticle structure of this state. Half-lives of 480±20 ns, 43±3 ns and 42±4 ns have been measured for the 2237 keV 9−, 2154 keV 7− states in 200Pb and the 2208 keV state in 202Pb, respectively; E2 transitions and g-factors of negative-parity states in even, neutron-deficient Pb isotopes are discussed.
